[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for observing a three-dimensional image displayed in a three-dimensional space, and more particularly to a three-dimensional image displayed in a three-dimensional space. Regarding a three-dimensional image observation device that can measure the dimensions of any part with a measuring tool such as a ruler, in the medical field,
The present invention relates to a three-dimensional image display device that can be used in the field of design, the field of mechanical design, and many other fields.

2. Description of the Related Art Conventionally, as a means for expressing an image so that an observer can perceive a stereoscopic effect, only the image information for the right eye is given to the right eye of the observer and the image information for the left eye is given to the left eye of the observer. Stereoscopic photography and stereoscopic television using the principle of allowing the observer to perceive a stereoscopic image by giving only a stereoscopic image to the observer. A so-called three-dimensional CG image, in which a three-dimensional image is displayed on a two-dimensional display screen by using, has come into practical use. However, from the three-dimensional image represented by the image display means as described above, Cannot obtain information that can be obtained when an observer observes a real object from various angles.

By the way, if it is possible to display a three-dimensional image in a three-dimensional space from which an observer can obtain the same information as when observing a real object from various angles, the field of medicine, the field of design, and the field of mechanical design can be improved. It can be used effectively in many fields and other fields. Now, in order to non-destructively obtain a two-dimensional figure showing a cross section of a different part of a stereoscopic image, conventionally, for example, an X-ray is irradiated onto a subject, and an X-ray transmitted through the subject is detected by an X-ray detection system. The X-ray projection data from multiple directions obtained in the above is subjected to image reconstruction processing by digital computation in a computer, and thereby a gray-scale image corresponding to the X-ray absorption in each section of the subject, that is, the inside of the subject, A sharp tomographic image is projected on the image plane of the cathode ray tube, or a clear tomographic image of the inside of the subject projected on the image plane of the cathode ray tube is photographed and used as a hard copy. 2. Description of the Related Art An X-ray CT (Computed X-Ray Tomography) technique is known which is capable of non-destructively obtaining a clear tomographic image of the inside of a subject. Tumors and hematomas inside the brain For standing also it can be easily known, it is as well known in practical use widely in the medical field.

The tomographic image obtained by the above-mentioned X-ray CT is a two-dimensional figure in each section of the subject to the last, but the tomographic image photograph (the two-dimensional figure of each part of the three-dimensional image) by the above-mentioned X-ray CT is individually obtained. It is desirable to assemble a three-dimensional image from a plurality of tomographic images instead of seeing the tomographic images. For example, tomographic images by X-ray CT are obtained from a subject at a predetermined pitch, and the obtained plurality of tomographic images are obtained. It has also been attempted to three-dimensionally grasp the internal structure of the subject from the photograph. For example, when a doctor tries to perceive as a three-dimensional image based on a plurality of tomographic images of a human body by X-ray CT, the most common method is to take a photograph of each section of the human body by X-ray CT all over. A doctor looked at the multiple tomographic images arranged side by side, and the doctor assembled it into a three-dimensional image in his head, but since the internal organs of the human body are complicatedly overlapped, It is natural that it is difficult to accurately and quickly grasp the three-dimensional structure by a simple method.

[0005] Instead of arranging a large number of tomographic images on a single plane as described above, by arranging the multiple tomographic images at positions corresponding to the original tomographic plane and viewing them simultaneously, a three-dimensional image can be obtained. It is thought that it is very easy to grasp the basic structure, but when the film of the tomographic image by X-ray CT is simply superimposed and observed so as to correspond to the position of the original tomographic plane, and observed. However, the transmittance of the film is poor, and the rear image is hardly seen because it is obstructed by the front image. That is, if the subject has a simple structure,
The above method may be used, but in the case of a simple structure, it is easy to look at each tomographic image and assemble three-dimensionally in the head. If the desired organs are overlapped in a complicated manner, the rear image is obstructed by the image on the near side and cannot be seen.

Conventionally, a stereoscopic image is displayed using a peritron cathode ray tube which is known as a device for displaying as a stereoscopic image the same information as that obtained when an observer looks at the real thing. Was tried. The peritron emits visible light by an electron beam emitted from an electron gun in a vacuum envelope composed of a case made of a transparent and confidential substance such as glass, a metal case, and a glass tube. And a part of a drive mechanism for driving and displacing the screen in the direction of the tube axis is sealed, and the screen is reciprocated back and forth in the tube axis direction. It is something that can be done. Then, the screen is driven in the tube axis direction at a repetition frequency that does not cause flicker to the human eye, for example, at a repetition frequency of 60 cycles per second or more, and is orthogonal to the tube axis direction in the three-dimensional figure to be displayed by the screen, and To deflect the electron beam in two orthogonal directions so that the two-dimensional cross-sectional view of the three-dimensional figure on each surface can be displayed on the screen for many surfaces arranged in the tube axis direction. By providing the required two deflection signals to the deflection system capable of performing the above-described operation, the two-dimensional sectional shape and the Lissajous figure corresponding to the two-dimensional sectional shape described above are drawn on the screen. A three-dimensional figure formed by stacking figures can be observed by human eyes as a three-dimensional image drawn by light.

With the above-mentioned peritron, it is possible to display a three-dimensional image as long as there is only an electric signal of a figure to be displayed. When viewed from the right, the three-dimensional image looks the same as when the real object is viewed from the right, and when viewed from the left, it looks as if the real object is viewed from the left. It is possible to display a three-dimensional image while being visible. However, since the peritron is a cathode ray tube, there is a problem of aberration and focusing of an electron beam, and it is difficult to smoothly operate a movable portion provided in a vacuum envelope for a long period of time. In a Peritron, when the screen was displaced in the tube axis direction, even when the electron beam was swung at the same deflection angle, the position of the spot on the screen changed. Sometimes the two-dimensional image drawn on the screen is small,
When the screen is displaced away from the electron gun side, the size of the graphic on the screen changes in such a manner that the two-dimensional image drawn on the screen becomes large, so that the displayed three-dimensional image is distorted. However, there are many problems, such as a problem that the display becomes more complicated, a problem that the deflection distortion exists, and a problem that it is difficult to make the display multi-color.

As a three-dimensional image display device free from the above-mentioned disadvantage of the peritron, the present applicant has disclosed a large number of two-dimensional light emitting elements as disclosed in Japanese Patent Publication No. Hei 5-74076. Vibrates the movable panel disposed in the direction substantially perpendicular to the panel surface, so that each tomographic image of the three-dimensional image displayed at each of different positions in the vibration direction can be sequentially displayed. On the surface of the movable panel opposite to the surface on which the large number of light emitting elements are arranged, a large number of light receiving elements for receiving the blinking control information of the large number of light emitting elements are arranged. Further, a movable structure is formed by integrally connecting the movable panel described above and a convex lens arranged in such a manner that a large number of light receiving elements in the movable panel are located at the position of the focal plane. Further, the movable structure described above is caused to vibrate in a direction substantially perpendicular to the surface of the movable panel. Further, the light receiving element group of the movable panel in the movable structure via the convex lens in the movable structure, In a three-dimensional display device comprising at least a two-dimensional image generating device capable of sequentially projecting light information of a two-dimensional figure of each cross section of a three-dimensional image to be light-emitting displayed by a light emitting element group of a movable panel in a movable structure, A large number of light emitting elements arranged two-dimensionally on the movable panel are divided into a plurality of groups, and a light emitting element driving circuit, a latch circuit, and a shift register for driving the light emitting elements belonging to each of the groups are provided as the above. A light-receiving element group to be provided in the movable panel is provided for each group in the movable panel, Light receiving elements of a number corresponding to the number of groups provided one by one for each shift register belonging to each group so that input signals to the shift registers belonging to each group can be individually received; In order to receive individual optical information corresponding to individual control information of a plurality of control information commonly used for control of the operation of each group, a plurality of pieces corresponding to the number of the plurality of control information described above are received. A light receiving element group of the movable panel in the movable structure using a movable panel having a configuration in which the light receiving elements are arranged, and a convex lens forming a movable structure together with the movable panel. As a two-dimensional image generating device that sequentially projects light information on the movable panel, light having predetermined information content is provided to each of the light receiving elements in the light receiving element group in the movable panel. A three-dimensional display device using a structure capable of giving information has been proposed.

In the three-dimensional display device disclosed in Japanese Patent Publication No. 5-74076, a good three-dimensional image can be displayed in a three-dimensional space without the above-mentioned problem of the peritron. However, the three-dimensional image displayed in the three-dimensional space by the three-dimensional display device is displayed in the three-dimensional space because the three-dimensional image is displayed by the light emitting element group of the movable panel in the movable structure. It is good to simply look at the three-dimensional image, but for the three-dimensional image displayed in the three-dimensional space, measure the dimensions in the depth direction of the three-dimensional image, the dimensions of any part in the three-dimensional image, etc. Even when trying to measure with a tool, the light emitting element group of the movable panel reciprocating at a high speed in a three-dimensional space and the measuring tool collide and the device is destroyed. That can not be carried out door becomes a problem. In the above-mentioned peritron,
Measurement of the size of the three-dimensional image displayed in the three-dimensional space in the depth direction and the size of an arbitrary part in the three-dimensional image displayed in the three-dimensional space as described above, such as a caliper and a ruler. Naturally, it is impossible to perform actual measurement with a tool because a three-dimensional image is formed in the vacuum envelope.

[0010] Therefore, the applicant's company has disclosed in
4.9798, JP-A-64-24243,
Another disclosed XYZ plotter, that is, a point light source is three-dimensionally displaced in a three-dimensional space to draw a three-dimensional image, and the three-dimensional image information of the three-dimensional image is converted to a fly-eye lens plate. Many proposals have been made regarding an XYZ plotter for recording on a two-dimensional photosensitive recording member provided at a focal plane. Then, a recorded photosensitive recording member in which three-dimensional image information is recorded on a two-dimensional photosensitive recording member by the XYZ plotter (the photosensitive recording member is subjected to a developing process after an exposure process such as a photographic film, for example). If it is necessary, it is needless to say that the recorded photosensitive recording member is obtained after the above-described development process). The light emitted from the member forms a three-dimensional reproduced image in a three-dimensional space. The whole of the three-dimensional reconstructed image is
If a real image exists in the three-dimensional space, any part of the three-dimensional reconstructed image existing in the three-dimensional space
The dimension in the depth direction and the dimension of an arbitrary part in the three-dimensional reconstructed image can be actually measured using a measuring tool such as a ruler.

[0011]

By the way, the aforementioned X
The two-dimensional photosensitive recording member used for recording the three-dimensional image information by the YZ plotter includes a three-dimensional image information of a three-dimensional image to be a subject. And XYZ
When a reproducing light is irradiated on a recorded photosensitive recording member in which three-dimensional image information is recorded on a two-dimensional photosensitive recording member by a plotter to form a three-dimensional reproduced image in a three-dimensional space, recording is performed. As described above, the reproduction light emitted from the completed photosensitive recording member is displayed as a three-dimensional reproduction image in the three-dimensional space by the fly-eye lens plate, but the three-dimensional image information is recorded by the XYZ plotter. In this case, the relative positional relationship between the two-dimensional photosensitive recording member and the fly's eye lens plate, and irradiating the recorded photosensitive recording member with reproduction light to form a three-dimensional reproduction image in a three-dimensional space If the relative positional relationship between the recorded photosensitive recording member and the fly-eye lens plate is not the same, a correct three-dimensional reproduced image cannot be displayed in the three-dimensional space.

The above-mentioned problems are caused by a fly-eye lens plate used for recording three-dimensional image information on a two-dimensional photosensitive recording member by the XYZ plotter, and a reproduction light beam on a recorded photosensitive recording member. And a fly-eye lens plate used for forming a three-dimensional reproduced image in a three-dimensional space by irradiating the three-dimensional image information to a two-dimensional photosensitive recording member by an XYZ plotter. The relative positional relationship between the fly-eye lens plate and the two-dimensional photosensitive recording member when recording the image, the recorded photosensitive recording member on which three-dimensional image information has been recorded by the XYZ plotter, and the three-dimensional An adjustment mechanism or a setting mechanism that enables the relative positional relationship with the fly-eye lens plate used for forming a three-dimensional reproduced image in space to be exactly the same, or a fly-eye lens plate And feeling It can be solved by or use members of the structure are integrated and sex recording member.

Using a member having a structure in which the fly-eye lens plate and the photosensitive recording member are integrated as described above,
When recording three-dimensional image information on a photosensitive recording member or displaying a three-dimensional reproduction image in a three-dimensional space from a recorded photosensitive recording member, the recorded photosensitive recording member and a fly-eye lens are used. Since there is no need to perform alignment with the board, it is convenient in terms of usability. By the way, in order to display a good three-dimensional reproduced image in a three-dimensional space, it is necessary that a fly-eye lens plate used as a component has good optical characteristics. However, the fly-eye lens plate used as a component of the member (recording medium) in which the fly-eye lens plate and the photosensitive recording member are integrated as described above is disposable. Due to the demands of the user and various other factors, the price of the recording medium is reduced, while maintaining the normal recognition of the three-dimensional image of a human, and
The need for the use of a fly-eye lens plate having optical characteristics such that a high-quality three-dimensional reconstructed image having a predetermined resolution can be produced in three-dimensional space has been required, so that a reasonable optical A fly-eye lens plate having characteristics will be employed.

Under the circumstances described above, it is difficult to use a fly-eye lens plate having a structure in which fly-eye lenses having a sufficiently large NA are arranged. When irradiated, the size of the three-dimensional reproduction image that can be formed in a good state in three-dimensional space,
For example, when a three-dimensional reconstructed image having a vertical dimension of the fly's eye lens plate of 10 cm or less (for example, 7.5 cm as an example) and larger than the above-described dimension is formed as a real image in a three-dimensional space. However, a viewer who looks at the three-dimensional reconstructed image will see a large phenomenon that the resolution of the part closer to oneself in the three-dimensional reconstructed image in the three-dimensional space is low and the resolution of the far part is high. You will feel great discomfort. In other words, when a human sees an actual three-dimensional object in daily life, the part of the three-dimensional object that is closer to himself is usually more visible than the distant part, Observation is performed while feeling confused that the three-dimensional reconstructed image can be seen in a state opposite to the way of feeling.

Here, as an example, in the case where the above-described three-dimensional reproduced image is used for medical treatment, a signal generated based on tomographic image data at a predetermined pitch obtained for a patient's organ is converted into the above-mentioned XYZ signal. Given to the plotter, the XYZ plotter draws a three-dimensional image of the patient's organ in a three-dimensional space by means of light spots, which is then placed on the approximately focal plane of the fly-eye lens plate. Considering the case where the recording member is recorded so that a recorded photosensitive recording member is irradiated with reproduction light to display a full-sized three-dimensional reproduced image of the patient's organ in a three-dimensional space, If the organ is the brain, the average size of the human brain is 15
cm, the 3D reconstructed image can be displayed in the 3D space only in a state that gives an uncomfortable feeling to the human brain when the above solution is followed. You can't. The above problem can be solved, for example, by using a fly-eye lens plate having a configuration in which fly-eye lenses having a sufficiently large NA are arranged. However, for the reasons already mentioned, such a solution cannot be adopted. Therefore, as another solution, for example, it is conceivable that only a three-dimensional reconstructed image of, for example, 10 cm or less with respect to the vertical dimension of the fly-eye lens plate is displayed in the three-dimensional space. This is not applicable to observation of a human brain having a size of about 15 cm.

Therefore, in the vertical direction of the two-dimensionally recorded photosensitive recording member disposed substantially at the focal plane of the fly-eye lens plate, a space in front of the fly-eye lens plate is three-dimensionally reproduced by a real image. An image is displayed, and a three-dimensional reproduced image by a virtual image is displayed in the space behind the fly-eye lens plate. There has been proposed an XYZ plotter for recording three-dimensional image information capable of displaying an image on a two-dimensional photosensitive recording member disposed substantially at the focal plane of a fly-eye lens plate (Japanese Patent Laid-Open No. Sho 64). -24243). And
When the XYZ plotter as described above is used, the size of a three-dimensional reproduced image that can be formed in a good state in a three-dimensional space when a recorded light-sensitive recording member is irradiated with reproduction light is increased. Observation of a human brain having a size of 15 cm, even when using a fly-eye lens plate with optical performance, for example, 7.5 cm with respect to the vertical dimension of the eye lens plate Can be performed in a good condition.

However, in the above case, the three-dimensional reconstructed image displayed in the three-dimensional space is not merely observed,
Even if the depth of the three-dimensional reconstructed image and the dimensions of an arbitrary part in the three-dimensional reconstructed image are actually measured using a measuring tool such as a ruler, the third order due to the virtual image of the space behind the fly-eye lens plate is obtained. It cannot be performed on the original reproduced image. Also, in the case of a three-dimensional reconstructed image displayed only by a real image in a three-dimensional space, when measuring a dimension or the like of an arbitrary part in the three-dimensional reconstructed image with a ruler or the like, the light-shielding object is not reconstructed by the three-dimensional reconstructed image. When entering, the 3D reconstructed image on the observer's side disappears from the light-shielding object, which is the opposite of what humans experience about actual 3D objects in everyday life . Therefore, a solution to the above-mentioned problems was required.

SUMMARY OF THE INVENTION According to the present invention, a recorded light-sensitive recording member in which three-dimensional image information is recorded on a light-sensitive recording member placed substantially on a focal plane of a fly-eye lens plate is reproduced. And the emitted light from the recorded photosensitive recording member is formed as a three-dimensional reproduction image in a three-dimensional space by a fly-eye lens plate, and the three-dimensional reproduction image is converted to the three-dimensional reproduction image. Observing a virtual image of a three-dimensional reproduced image reflected by a half mirror provided in an optical space between an image and an observer, or a tertiary image that can observe a three-dimensional reproduced image transmitted through the half mirror The original image observation device is configured. Also,
When producing a recorded photosensitive recording member used for forming a three-dimensional reproduction image to be displayed in a three-dimensional space, a three-dimensional object prepared for recording three-dimensional image information on the photosensitive recording member, With three or more alignment markers attached, a recorded photosensitive recording member on which three-dimensional image information is recorded is obtained, and the recorded photosensitive recording member is irradiated with reproduction light of diffused light. The three-dimensional image is formed in a three-dimensional space by a fly-eye lens plate as a three-dimensional reconstructed image, and reflected by a half mirror provided in an optical space between the three-dimensional reconstructed image and an observer. The position of the virtual image of the reconstructed image and the position of the three-dimensional object are aligned with each other using the positioning marker, and the virtual image of the three-dimensional reconstructed image and the three-dimensional Combine with the object so that you can observe it To. A half mirror provided in the optical space between the three-dimensional reproduction image and the observer,
From the surface surrounded by the intersection of the plane intersecting the perpendicular at a predetermined position on the perpendicular of the center position of the recorded photosensitive recording member and the outer peripheral surface of the three-dimensional shape formed corresponding to the viewing zone A member having a through hole having a small size and shape is provided in the optical space between the recorded photosensitive recording member and the observer so that spurious and the like do not enter the observer's eyes. Further, the three-dimensional image observation apparatus supports the three-dimensional position and the rotation by supporting devices each having three degrees of freedom. The position of the virtual image of the three-dimensional reproduced image reflected by the half mirror provided in the optical space between the three-dimensional reproduced image and the observer is generated at a position separated by a predetermined distance from the half mirror. To control the intensity of the reproduction light to be set to a specific intensity related to the luminance of the three-dimensional object, or to control the intensity of the reproduction light to a specific intensity related to the luminance of the three-dimensional object. The on / off control of the reproduction light in the state set to is performed. Further, the intensity of the illumination light is controlled so that the luminance of the three-dimensional object can be switched between a specific value related to the intensity of the reproduction light and a value larger than the specific value, or the half value described above is used. The configuration is such that the opening and closing of the mirror can be controlled, and the entire housing of the three-dimensional image observation device can be controlled so as to be able to freely enter and exit the optical space between the observer and the three-dimensional object.

[0019]

When the recorded photosensitive recording member, on which the three-dimensional image information is recorded, is irradiated with the reproduction light on the photosensitive recording member placed substantially on the focal plane of the fly-eye lens plate, the recorded image is recorded. The light emitted from the photosensitive recording member is displayed as a three-dimensional reproduced image in a three-dimensional space by the fly-eye lens plate. The three-dimensional reproduced image can be observed as a virtual image of a three-dimensional reproduced image reflected by a half mirror provided between the three-dimensional reproduced image and an observer, or a three-dimensional reproduced image transmitted through the half mirror. When observing the depth dimension of the three-dimensional reconstructed image and the dimension of an arbitrary part in the three-dimensional reconstructed image with a ruler or the like, even if the light-shielding object is put in the three-dimensional reconstructed image, Observation and actual measurement can be performed in a state where the three-dimensional reproduced image on the observer side with respect to the light-shielding object does not disappear, and a virtual image of the three-dimensional reproduced image obtained by reflecting the three-dimensional reproduced image by a half mirror. Observer (eg doctor)
And a person (patient) observing the three-dimensional reconstructed image transmitted through the half-mirror observes an image in which the left and right (or up and down) are opposite to each other. Can be observed at the same time.

In producing a recorded photosensitive recording member used for forming a three-dimensional reproduced image to be displayed in a three-dimensional space, a three-dimensional image prepared for recording three-dimensional image information on the photosensitive recording member is prepared. With three or more alignment markers attached to the object, the recorded light-sensitive recording member on which the three-dimensional image information is recorded is irradiated with reproduction light, and the fly-eye lens plate is placed in the three-dimensional space. It is formed as a three-dimensional reproduction image by the position of the virtual image of the three-dimensional reproduction image reflected by a half mirror provided between the three-dimensional reproduction image and the observer, and the position of the three-dimensional object and When the virtual image of the three-dimensional reconstructed image and the three-dimensional object are observed by synthesizing the virtual image of the three-dimensional reconstructed image in a state where the positions are aligned with each other using the marker for alignment, the inside of the opaque three-dimensional object , Among the three-dimensional objects Structure can be observed as an image in the state fitted in.

For example, if the three-dimensional object is a human head and the virtual image of a three-dimensional reconstructed image synthesized with the three-dimensional object is the above-mentioned human brain, the observer will be able to observe the brain within the human head. Can be observed even without cutting the head. Therefore, as described above, if a virtual image of a three-dimensional reconstructed image of the human brain is synthesized and displayed on the human head, the observer accurately perceives the state of the brain in the human head. In the state, you can easily perform brain surgery,
For example, in an operation such as a car accident where a large number of pieces of glass are pierced, surgery is also performed by synthesizing a three-dimensional image showing the position of the piece of glass inside the human body with a corresponding part of the patient's body. It can be done very easily. Then, the virtual image position of the three-dimensional reproduction image reflected by the half mirror provided between the three-dimensional reproduction image and the observer is generated at a position separated by a predetermined distance from the half mirror. The above-mentioned operation can be easily performed.

A half mirror provided between the three-dimensional reproduced image and the observer; and a plane intersecting the perpendicular at a predetermined position on a perpendicular to the center of the recorded photosensitive recording member. A member having a through-hole having a size and shape smaller than the surface surrounded by the intersection of the three-dimensional outer surface formed corresponding to the viewing zone is provided between the observer and the recorded photosensitive recording member. This makes it possible to obtain a three-dimensional reconstructed image without spurious or the like. The three-dimensional image observation device described above, for three-dimensional position and rotation,
Since each of the three-dimensional objects is supported by a supporting device having three degrees of freedom, when the virtual image of the three-dimensional reproduced image and the three-dimensional object are combined and observed, the three-dimensional object is placed inside the opaque three-dimensional object. Can be easily observed as an image in a state where the internal structure is well fitted.

The virtual image of the three-dimensional reconstructed image and the three-dimensional object are synthesized so that the three-dimensional object can be observed inside the opaque three-dimensional object as an image in which the internal structure of the three-dimensional object is well fitted. When observing a 3D object, the light intensity of the reproduction light and the light intensity of the illumination of the 3D object can be controlled to easily observe the virtual image of the 3D reproduced image and the 3D object combined. State. Further, by controlling the light intensity of the reproduction light and the light intensity of the illumination of the three-dimensional object, a virtual image of the three-dimensional reproduction image is obtained.
The light intensity of the reproduction light, the light intensity of the illumination of the three-dimensional object, and the like are set in a state in which observation in a state where the three-dimensional object is synthesized can be easily performed, and the reproduction light is turned on and off. Control, or control to switch the light intensity of the illumination of the three-dimensional object between the set light intensity and the light intensity higher than the set light intensity, or open / close control of the half mirror Or by moving the entire housing of the three-dimensional image observation apparatus freely into and out of the optical space between the observer and the three-dimensional object, the virtual image of the three-dimensional reproduction image and the three-dimensional object Can be easily switched between a state in which the three-dimensional object is observed and a state in which the three-dimensional object is observed.

FIG. 23 is an example of a main portion for explaining the configuration principle of an XYZ plotter having a configuration that does not cause the above-mentioned problem. In FIG.
A fly-eye lens plate whose focal plane is a plane including any two coordinate axes in an X, Y, Z orthogonal coordinate system.
M is a photosensitive recording member provided at the focal plane of the fly-eye lens plate FEL, and PPS is to be recorded in a three-dimensional space in front of the fly-eye lens plate FEL. A point light source which is lit at a position corresponding to the shape of the three-dimensional image,
S is a means for driving it three-dimensionally, for example, as shown in FIG.
1 so that it can be displaced and driven to any predetermined position in the three-dimensional space on the front surface of the fly-eye lens plate FEL by the three-dimensional displacement driving means having the configuration as described with reference to FIG. I have.

In FIG. 23, SM is formed on the front surface of the fly-eye lens plate FEL by a three-dimensional displacement driving means having the same configuration as the three-dimensional displacement driving means shown in FIG. 18, for example. The limiting member for the divergence direction of the light with respect to the light emitted from the point light source PPS which can be displaced and driven to an arbitrary predetermined position in the three-dimensional space, and the limiting member SM for the divergence direction of the light is: For the photosensitive recording member PSM to be set on the focal plane of the fly-eye lens plate FEL composed of an array of a plurality of single-eye lenses, each single-eye lens in the fly-eye lens plate FEL is a fly-eye lens plate. Individual areas are set so as to have a one-to-one correspondence with the above-described single-lens existence areas with the same planar shape and dimensions as the individual-lens existence areas individually occupied in the eye lens plate FEL ( Figure 23, see the area indicated by P in FIG. 14) when the photosensitive recording member P
The point light source PPS described above is set so that light passing through a single lens other than the single lens corresponding to the individual area is not incident on the individual areas set in the SM.
It is configured to perform an operation of restricting the direction of divergence of light from the camera.

The above point is specifically described as follows. The fly-eye lens plate FEL, which is constituted by an array of a plurality of single-lenses, has an existence area in which the multiple single-lenses used to construct the fly-eye lens plate exhibit predetermined geometric dimensions. In many cases, the presence area of each single-lens is arranged so as to follow a predetermined arrangement pattern, and the existence of each single-lens in the fly-eye lens plate FEL The area is formed, for example, in a grid pattern, or in a honeycomb pattern, for example.

For the photosensitive recording member PSM to be set on the focal plane of the fly-eye lens plate FEL, each single lens in the fly-eye lens plate FEL is placed in the fly-eye lens plate FEL. The individual areas are set so as to correspond one-to-one with the existing area of each of the single-lenses with the same planar shape and dimensions of the existing area of the single-eye lens individually occupied by the photosensitive recording member. In the individual regions set as described above in the PSM, the incident light beams having the maximum incident angles of the incident light beams incident on the region from the monocular lens corresponding to the regions (light beams PLl and PLr in FIG. 14) Each of the individual eye lenses is assumed to be in a state where the light incident on each of the eye lenses is limited to light rays included in the range of the angle θ in FIG. 14 so that the light reaches the boundary of the region. It will be incident on the lens Thus, the divergence direction of the light emitted from the point light source PPS is limited by the divergence direction limiting member SM.

The light divergence direction restricting member SM used to restrict the divergence direction of the light radiated from the point light source PPS is a fly-eye constituted by an array of a plurality of single-lenses. When the lens plate FEL has a square existence area of a large number of single-lenses used in its configuration and the existence area of each single-lens follows an array pattern like a grid, a square A configuration in which an opening is provided may be used,
A fly-eye lens plate FEL composed of an array of a plurality of single-lenses has a regular hexagonal shape in the existence area of the multiple single-lenses used in the configuration. When the existence area follows a honeycomb-like arrangement pattern, the light divergence direction restricting member SM used to restrict the divergence direction of the light emitted from the point light source PPS is a regular hexagonal shape. A configuration in which an opening is provided may be used.

A fly-eye lens plate FEL is formed by arranging and arranging a large number of spherical single-eye lenses arbitrarily using a spherical single-eye lens which is easy to produce a high-performance single-eye lens. When the lens plate FEL is used,
As the restricting member SM of the divergence direction of the light used for restricting the divergence direction of the light emitted from the point light source PPS, one having a configuration in which a circular opening having a predetermined diameter is provided is used. . In the above description, as the light diverging direction restricting member SM used to restrict the diverging direction of the light emitted from the point light source PPS, one having a configuration having an opening of a predetermined shape is used. However, any limiting means capable of giving a directional characteristic to the light emitted from the point light source PPS in such a manner that the diverging direction of the light can be limited in a required limiting manner may be applied. It is.

As described above, when the divergence direction of the light radiated from the point light source PPS is restricted by the light divergence direction restricting member SM, the lighting state of the point light source PPS is controlled by the computer, and the fly is controlled. Within a predetermined range in a three-dimensional space in front of the eye lens plate FEL, the shape of a three-dimensional image to be recorded is displayed as a continuous linear light locus, Alternatively, when the shape of the three-dimensional image to be recorded is displayed by the arrangement of the light spots, the light emitted from the point light source PPS emits the light divergence shown in FIG. When the divergent direction is restricted by the direction restricting member SM, the light is incident on each single-lens of the fly-eye lens plate FEL, so that the photosensitive recording member PS provided on the focal plane of the fly-eye lens plate FEL. 23, an image of the point light source PPS is formed for each individual lens (single lens) within a predetermined range of the compound eye lens FEL, and is located on the focal plane of the fly-eye lens plate FEL in FIG. A predetermined number of areas (FIG. 23) in the photosensitive recording member PSM

The position is different from the image forming position of the image of the point light source PPS shown in FIG. 23, and the photosensitive recording member PSM installed on the focal plane of the fly-eye lens plate (compound eye lens) FEL has: Light from the point light source PPS in the above-mentioned compound eye lens FEL
For each individual lens (single lens) into which (light within the angle θ of the light emitted from the point light source PPS) is incident,
The image of the point light source PPS is formed and recorded at a position corresponding to the lighting position of each point light source PPS in the three-dimensional space on the front surface of the fly-eye lens plate FEL on a one-to-one basis. A fly-eye lens plate FEL is used for the recording member PSM.

The visible range of the reproduced image PPSp and the visible range of the spurious image PPSp〓1 never overlap, and the straight line f and the straight line h are parallel for the same reason as described above, and the spurious image PPSpr1 is visible. The range and the range in which the spurious image PPSpr2 can be seen never overlap, and, of course, the reproduced image PPSp
And the range in which the spurious image PPSpr2 is visible never overlaps. Similarly, the straight line e and the straight line g
Are parallel to each other, so that the visible range of the spurious image PPSp # 1 and the visible range of the spurious image PPSp # 2 never overlap, and the visible range of the reproduced image PPSp and the visible range of the spurious image PPSp # 2 never overlap. Because there is no.

The X described with reference to FIGS.
In the YZ plotter, a three-dimensional image to be recorded formed by the movement locus of the point light source in the three-dimensional space in front of the fly-eye lens plate FEL is set on the focal plane of the fly-eye lens plate FEL. A recorded photosensitive recording member PSMp in which the position information of the point light source PPS at each position in the three-dimensional space on the front surface of the fly-eye lens plate FEL is recorded as described above on the photosensitive recording member PSM. By irradiating the reproduced light of the diffused light as shown in FIG. 25, the reproduced image reproduced in the three-dimensional space on the front surface of the fly-eye lens plate FEL is targeted for recording. Point light source P
A three-dimensional range in which a reproduced image PPSp corresponding to PSp can be recognized by an observer (a part indicated by an arrow θ in FIG. 25..., A visual field), and fake reproduced images PPSpr1 and PPSpr.
, PPSp # 1, PPSp # 2 ... do not overlap with the range that can be recognized by the observer (illustrated in FIG. 25 by arrows A, B, C, D, etc.).

Then, the observer's eye E is pointed by the arrow θ in FIG.
23, the observer recognizes only the light spot PPSp reproduced at a position corresponding to the position of the true point light source PPS in FIG. Although it was possible to correctly view the original three-dimensional image to be recorded over a wide range, the range in which the three-dimensional image to be recorded can exist in the XYZ plotter described above is shown in FIG. (a) is limited to the range shown as the image area, that is, the pyramid-shaped three-dimensional space in front of the fly-eye lens plate FEL, and extends to the space behind the fly-eye lens plate FEL. It was not possible to record a three-dimensional image on the fly-eye lens plate FEL in a state where a three-dimensional image to be recorded exists, and to reproduce the three-dimensional image.

That is, the two-dimensional photosensitive recording member PSM of the recording medium used for recording the three-dimensional image information by the XYZ plotter described above has the three-dimensional image of the three-dimensional image as the subject. Eye lens plate F with image information fly
An image is formed by each fly's eye lens in the EL, and reproduction light is applied to a two-dimensionally recorded photosensitive recording member PSMp in a recorded recording medium in which three-dimensional image information of a subject is recorded. When a three-dimensional reproduced image is formed in a three-dimensional space, the reproduced light emitted from the recorded photosensitive recording member PSMp in the recorded recording medium is converted into a three-dimensional reproduced image by the fly-eye lens plate FEL. However, when the three-dimensional image information is recorded by the XYZ plotter described above, the recording is limited to only the pyramid-shaped three-dimensional space in front of the fly-eye lens plate FEL. The recorded photosensitive recording member PSMp on the recorded recording medium is irradiated with the reproduction light of the diffused light to thereby record the recorded photosensitive recording member PSMp.
A three-dimensional space in which light emitted from the lens is displayed as a three-dimensional reproduction image by the fly-eye lens plate FEL is a fly-eye lens plate FEL.
It exists between the EL and the observer.

By the way, when the recorded photosensitive recording member PSMp in the recorded recording medium is irradiated with the reproduced light of the diffused light, the three-dimensional reproduced image displayed in the three-dimensional space by the fly-eye lens plate FEL. Depends on the optical performance of the fly-eye lens plate FEL used. By the way, when observing the three-dimensional reconstructed image displayed in the three-dimensional space, the three-dimensional reconstructed image is perceived as a feeling that is opposite to the feeling that a human sees a three-dimensional image everyday. You. In other words, when you look at a three-dimensional object placed in front of you, it is normal for the part of the three-dimensional object that is closer to you to be clearly visible and the part that is far from you to look blurred. In addition, the above-described three-dimensional reproduced image displayed in the three-dimensional space has an unnatural feeling in which a portion near the user is blurred and a portion away from the user is clearly visible. ing.

When the three-dimensional reproduced image displayed in the three-dimensional space is viewed, the above-mentioned unnaturalness is determined by the size of the three-dimensional reproduced image displayed in the three-dimensional space and the size of the fly's eye. This is determined by the optical performance of the lens plate FEL. For example, if the optical performance of the fly-eye lens plate FEL is determined, the size of the three-dimensional reproduced image displayed in the three-dimensional space is small. Indeed, the degree to which the unnaturalness is felt is small, and if a large three-dimensional reproduction image is to be displayed as a natural feeling in a three-dimensional space,
The fly-eye lens plate FEL to be used is expensive with good optical performance.

For example, when the above-described three-dimensional reproduced image is used for medical treatment, it is assumed that a recording medium having a structure in which a fly-eye lens plate FEL and a two-dimensional photosensitive recording member PSM are integrated is adopted. Considering the expected price of the recording medium at that time, the fly-eye lens plate used for the recording medium has such a size that a three-dimensional reproduced image of, for example, 10 cm or less can be favorably displayed with respect to its vertical dimension. However, if the recorded recording medium is irradiated with reproduction light to display a full-size three-dimensional reproduced image of the patient's organ in a three-dimensional space, if the patient's organ is a brain However, since the average size of the human brain is about 15 cm, the three-dimensional reproduction of the human brain is performed only in a state that gives a sense of incongruity to the observer when the above solution is followed. Images are displayed in three-dimensional space Rukoto it comes to can not.

In the vertical direction of the surface of the recording medium having the structure in which the fly-eye lens plate FEL and the two-dimensional photosensitive recording member PSM are integrated, a three-dimensional image based on a real image is provided in the space in front of the recording medium surface. A reproduced image is displayed in both the front and rear spaces of the recording medium surface such that a reproduced image is displayed and a three-dimensional reproduced image by a virtual image is displayed in a space behind the recording medium surface. By recording such three-dimensional image information on a two-dimensional photosensitive recording member PSM,
Photosensitive recording member PS recorded on recorded recording medium
When the reproduction light is irradiated onto Mp, the size of the three-dimensional reproduction image that can be formed in a good state in the three-dimensional space is:
A recording medium using a fly-eye lens plate FEL having an optical performance of, for example, 7.5 cm with respect to the vertical dimension of the fly-eye lens plate FEL has a size of 15 cm. Focusing on the fact that the brain can be observed in a good state, an XYZ plotter having a configuration as shown in FIG. 26 has been proposed.

In FIG. 26, MB is a machine base, and a fly-eye lens plate FEL is installed on the machine MB similarly to the XYZ plotter shown in FIG. And a photosensitive recording member PSM disposed so as to be located at the focal plane of the eye lens plate FEL. The fly eye lens plate FEL and the photosensitive recording member PSM are also shown in FIG. XYZ described with reference
As described above for the plotter can be used. In the XYZ plotter having the configuration shown in FIG.
Is a transfer body that is displaced and driven by the operation of a drive device DRA described later in a three-dimensional space in front of the fly-eye lens plate FEL. The light source PS and the optical system Lc And are stored. The optical system Lc housed in the transfer body Fyb converges the light emitted from the light source PS to form a converging point PSI, such as a convex lens or a concave mirror, and then forms the condensing point PSI. A configuration having a function of dispersing a light beam from the point PSI is used.

The light source PS housed in the transfer body Fyb focuses light emitted from, for example, an incandescent lamp, a discharge lamp, or any other light-emitting source by a condenser lens, and a pinhole is formed at the condensing point. A divergent light beam emitted from the point light source PS is converged by a convex lens constituting the optical system Lc to form an image of the point light source PS at a converging point PSI. Image. The light condensing point PSI obtained by converging the light beam divergent from the point light source PS by the optical system is a new light source PSI (new point light source PSI), and the divergent light beam from the light source PSI is a fly-eye lens plate FEL. Is illuminated. The converging point PSI formed as the new point light source PSI is transmitted through the transfer body Fyb so as to emit light at a position corresponding to the shape of the three-dimensional image to be recorded. 2 is driven by the driving device DRA.
The entire XYZ plotter shown in FIG. 6 is used in a state of being housed in a dark box.

The transfer body Fyb is a fly-eye lens plate F
The driving device DRA can be driven to be displaced to any position within a predetermined range in a three-dimensional space on the front surface of the EL. This driving device DRA may have the same configuration as the driving device DRA of the XYZ plotter described with reference to FIG. FIG. 2
6 is a transfer body, and this transfer body Fyb is XY
It is transported in the Y-axis direction by the drive rotation of the stepping motor My along the rail member Ry provided to extend in the Y-axis direction in the Z orthogonal coordinate system. Drive device DR for point light source in XYZ plotter shown in FIG. 26
A represents each of the transfer bodies Fx and Fy in the X, Y, and Z axis directions described above.
b, Fz, the respective stepping motors Mx, M
yb and Mz are rotationally driven in accordance with a drive signal supplied from a computer, so that the transfer body Fy in the Y-axis direction is driven.
b, the position immediately before the lowermost end Fybe thereof comes into contact with the surface of the fly-eye lens plate FEL is the lowermost end, and the position at which the transport body Fz in the Z-axis direction reaches the upper end of the rail member Rz is the upper end. The movable range in the vertical direction and each transfer body F
As long as x and Fyb can move back and forth and right and left along the rail members Rx and Ry, they can be displaced and driven to any position in the three-dimensional space on the front surface of the fly-eye lens plate FEL.

In FIG. 26, the transfer member Fyb in the Y direction is a fly-eye lens plate F as shown in FIG.
When the light-collecting point PSI, which is a new point light source, is located above the fly-eye lens plate FEL at a position separated upward in the space in front of the EL, The light diverging from the light point PSI is reflected by the fly-eye lens plate F
The above-described compound eye lens plate FEL is applied to a photosensitive recording member PSM which is focused on each single eye lens in the EL and is disposed on the focal plane of a fly eye lens plate (compound eye lens plate) FEL.
Focus point (point light source) for each individual lens (single lens) in
An image of the PSI is formed and recorded.

In the XYZ plotter shown in FIG. 26, the transfer member Fyb in the Y direction is located at a lower position in the space in front of the fly-eye lens plate FEL as shown in FIG. Focus point PS to be a point light source
When I is located below the position of the fly-eye lens plate FEL, that is, when the fly-eye lens plate FEL is located at a position higher than the position of the light-converging point PSI formed by the light-flux converging action of the optical system Lc. In the case where the fly-eye lens plate FEL is not present when the optical system Lc is installed near the optical system Lc, a virtual light-converging point generated at the position of PSI ′ in the space shown in FIG. A light beam focused on the PSI ′ (a light beam having the same direction as the light beam diverging from the virtual light-converging point PSI ′) is focused on each individual eye lens on the fly-eye lens plate FEL. The information is recorded for each individual lens (single lens) of the above-mentioned compound eye lens plate FEL on the photosensitive recording member PSM provided on the focal plane of the fly-eye lens plate (compound eye lens plate) FEL.

That is, as shown in FIG. 27, the focal point PSI recorded on the photosensitive recording member PSM installed on the focal plane of the fly-eye lens plate (compound eye lens plate) FEL in the recording mode as described above. The light intensity and position information of the (point light source), or the light intensity and position information of the virtual converging point PSI ′ as shown in FIG. By the development processing, only the light intensity and position information of the focal point PSI (point light source) in FIG. 27 or the light intensity and position information of the virtual focal point PSI ′ in FIG. 28 become transparent. A recorded photosensitive recording member PSMp that has been developed in such a manner that the other portions are black, that is, only the image portion of the point light source is transparent and the other portions are black. With the developed recorded photosensitive recording member PSMp It is.

FIG. 29 shows that the transfer member Fyb in the Y direction is located at a lower position in the space in front of the fly-eye lens plate FEL as described above, and the condensing point P serving as the new point light source described above.
SI is a position below the fly-eye lens plate FEL,
In other words, if the fly-eye lens plate FEL does not exist, the individual eyes constituting the fly-eye lens plate FEL in the light beam converging on the virtual light-converging point PSI 'generated in the space when the fly-eye lens plate FEL does not exist. The luminous flux of each lens is focused for each individual eye lens, and the photosensitive recording member P set on the focal plane of the fly-eye lens plate (compound eye lens plate) FEL described above.
FIG. 7 illustrates a state in which an image is recorded and recorded on the SM for each of the individual eye lenses constituting the fly-eye lens plate FEL.

Referring to FIG. 29, the luminous flux of each individual lens constituting the fly-eye lens plate FEL in the luminous flux converging to the virtual converging point PSI 'in FIG. The above-mentioned fly-eye lens plate is focused for each eye lens.
(Compound eye lens plate) The direction of the light beam imaged and recorded on the photosensitive recording member provided on the focal plane of the FEL, and the light beam diverging from the virtual focusing point PSI 'in FIG. The above-mentioned compound eye lens plate FE is attached to a photosensitive recording member PSM which is focused on each individual eye lens in the FEL and is installed on the focal plane of the fly eye lens plate (compound eye lens plate) FEL.
It can be seen that the direction of the luminous flux at the time of image formation and recording is the same for each lens (single lens) in L.

In FIG. 29, the luminous flux incident on each single-lens constituting the fly-eye lens plate FEL is not perfect parallel light, but is a virtual converging point PSI 'in the figure.
FIG. 29 shows the positions of the light-converging points when the light beams incident on the individual single-lens lenses are focused on the individual single-lens lenses because the light beams are focused on the individual single-lens lenses. The fly-eye lens plate (compound lens plate) FEL as described above
The focal plane of the fly-eye lens plate (compound eye lens plate) FEL is shifted to the front side from the position of the photosensitive recording member provided on the focal plane of the fly-eye lens plate (multiple lens plate) FEL as shown in FIG. At the position of the photosensitive recording member installed in the camera, an image of a slightly blurred light spot having a large diameter is recorded. This has the following advantages during reproduction.

That is, as described with reference to FIG. 29, an image of a light spot having a large diameter slightly blurred on the photosensitive recording member PSM provided on the focal plane of the fly-eye lens plate (compound eye lens plate) FEL. When reproduction is performed by irradiating diffused light (not shown in FIG. 30) from the back side of the recorded photosensitive recording member PSMp obtained by developing the photosensitive recording member in the recorded state, Eye lens plate (compound eye lens plate) FEL
An observer looking at the fly-eye lens plate (multiple-lens plate) FEL with both eyes positioned in the space in front of the image of the large-diameter light spot slightly blurred as described above is recorded. Since a light beam as shown in FIG. 30 showing a slight spread that has passed through the recorded image on the recorded photosensitive recording member PSMp in the depressed state is given, the observer can reverse the overall light beam given the slight spread. When the reproduced image is perceived by tracing, it is assumed that the reproduced image exists at a position deeper than the position of the fly-eye lens plate (multiple lens plate) FEL, that is, the reproduced image exists at PSIp in FIG. In addition to being able to perceive,
As described above, the observer to whom a light beam showing a slight spread is given after passing through the recorded image on the recorded photosensitive recording member PSMp in the state where the image of the light spot having a large diameter slightly blurred is recorded is observed during reproduction. The light spot of the reproduced image does not become invisible due to the displacement of the eye position of the user.

The above-described recorded photosensitive recording member PSMp
And a fly-eye lens plate FEL having the same configuration as the fly-eye lens plate FEL used at the time of recording so that the relative positional relationship between the two is the same as that at the time of recording. In addition, when diffused light is emitted from the light source to the recorded photosensitive recording member PSMp from the side opposite to the fly-eye lens plate FEL, the light transmitted through the recorded photosensitive recording member PSMp is reflected by the fly-eye lens plate FEL. When the light is focused on each individual eye lens, an observer at a position apart from the eye lens perceives that a point of light exists at the focused position. Therefore, assuming that images of point light sources at a plurality of positions three-dimensionally displaced in a three-dimensional space are recorded as the recorded photosensitive recording members PSMp, the recorded images are recorded on the recorded photosensitive recording members PSMp. The image at each position of the point light source was changed to a fly-eye lens plate FEL.
Are focused for each individual eye lens in the above, and real images are respectively formed at the original point light source positions in the three-dimensional space where the fly-eye lens plate FEL exists. When a person at the position views, the entire line of light or the point of light appearing at the position of the real image in the three-dimensional space can be perceived as a three-dimensional image of light.

FIG. 31 shows the XYZ plotter shown in FIG.
FIG. 26 is a diagram for explaining a difference in an image area between the XYZ plotter described with reference to FIGS. 18 to 25 and FIG.
In the image area of the XYZ plotter shown in FIG. 26 shown in FIG. 26B, the optical system Lc used to form a point light source for irradiating the fly-eye lens plate FEL with the divergent light is the fly. In order to spread the light beam to the position of the light condensing point (virtual light condensing point) PSI'd by the optical system Lc in a state in which the light beam is set at a position just before coming into contact with the eye lens plate FEL, FIG. 31 has only a pyramid-shaped image area in a space in front of the lens plate FEL.
It is clear that the image area can be enlarged to twice the image area of the XYZ plotter described with reference to FIGS. 18 to 25 shown in FIG. Note that PS in the figure
Iu indicates the uppermost position of the focal point of the light beam by the optical system Lc.

FIG. 32 shows an optical system Lc in which the deepest part of the three-dimensional image to be recorded / reproduced is used to form a point light source for irradiating the fly-eye lens plate FEL with divergent light. As shown in FIG. 31 (b), the light beam condensing point (point light source by virtual condensing point) PSI of the light beam by the optical system Lc in a state where the light beam is made just before coming into contact with the fly-eye lens plate FEL. In the case shown in FIG. 32A where the distance β has a relation of β <α compared to the distance α between the position “′” and the distance α to the lens plate FEL, An optical system Lc used to form a point light source for irradiating the lens plate FEL with divergent light has a focal length β and a fly-eye lens plate FEL whose diameter is β.
32 can be smaller than the size of
(B) of FIG.}.

Next, in order to prevent a spurious image or a ghost image from being generated in the three-dimensional reproduced image recorded by the XYZ plotter shown in FIG. 26, an arbitrary image in the three-dimensional space where the fly-eye lens plate FEL exists is provided. A configuration example for limiting the diverging direction of the divergent light emitted from the point light source PSI that can be driven to be displaced to the predetermined position by the three-dimensional displacement driving means will be described. In the XYZ plotter shown in FIG. 26, by limiting the aperture of the optical system Lc housed in the transfer body Fyb, the emission angle of the divergent light beam irradiating the fly-eye lens plate FEL can be limited. The optical system Lc is set by setting the shape and size of the lower end portion Fybe of the transfer body Fyb in the Y direction shown in FIGS. 27 and 28 in a predetermined manner.
It is also possible to limit the emission angle of the divergent light beam emitted from the light source.

The above-mentioned restriction on the exit angle of the divergent light beam irradiating the fly-eye lens plate FEL is set on the focal plane of the fly-eye lens plate FEL which is constituted by an array of a plurality of single-lenses. Regarding the photosensitive recording member PSM to be designed, the planar shape and dimension of each of the monocular lenses in the fly-eye lens plate FEL are the same as the planar shape and dimension of the area where the monocular lens is individually occupied in the fly-eye lens plate FEL. When the individual areas are set so as to correspond one-to-one with the existence areas of the individual eye lenses described above, the photosensitive recording member P
The point light source PSI described above is set so that light passing through a single-lens lens other than the single-lens lens corresponding to the individual region is not incident on the individual regions set in the SM.
This is done in order to limit the direction in which light diverges.

The fly-eye lens plate FEL composed of an array of a large number of single-lenses has a plurality of single-lenses used to form the fly-eye lens plate, each having a predetermined shape and size. It is often configured as a state where the existence areas of the individual eye lenses are arranged so as to follow a predetermined arrangement pattern in a state having the existence areas as shown in FIG. The area in which the single-lens exists is formed, for example, in a grid-like array pattern, or in a honeycomb pattern, for example.
For the photosensitive recording member PSM to be set on the focal plane of the EL, the existence of the monocular lenses occupied by the individual eye lenses in the fly-eye lens plate FEL individually in the fly-eye lens plate FEL Individual areas are set so as to correspond one-to-one with the area where each of the monocular lenses is present, with the same plane shape and dimensions as the area, and the individual areas set as described above on the photosensitive recording member PSM. Then, the incident light beam having the maximum incident angle of the incident light beam incident on the region from the single-lens lens corresponding to the region is incident on each of the single-lens lenses so as to reach the boundary of the region. The divergence direction of the light radiated from the point light source is limited so that the light is incident on each single lens as if the angle of incidence of the light was restricted.

As a member for limiting the direction of divergence of light used to restrict the direction of divergence of light emitted from the point light source PSI, a fly-eye lens constituted by an array of a plurality of single-lenses is used. The plate FEL has a square aperture when the area of each of the plurality of monocular lenses used in the configuration of the plate FEL follows a grid-like array pattern. Embodiments may be used. Further, a fly-eye lens plate FEL composed of an array of a large number of single-eye lenses is
If the area of each of the plurality of monocular lenses used in the configuration follows an array pattern like a honeycomb, the divergence direction of the light emitted from the point light source PSI is limited. A member having a configuration in which a regular hexagonal opening is provided may be used as the light diverging direction restricting member used for this purpose.

A fly-eye lens plate FEL is a fly-eye lens formed by arbitrarily arranging and assembling a plurality of spherical eye-lenses using a spherical eye-lens which is easy to produce a high-performance eye-lens. When the lens plate FEL is used,
As a restricting member of the divergence direction of the light used for restricting the divergence direction of the light emitted from the point light source PSI, a member having a configuration in which a circular opening having a predetermined diameter is provided is used. In the above description, the point light source P
As a member for restricting the divergence direction of light used for restricting the divergence direction of light radiated from the SI, a configuration having an opening having a predetermined shape was used. Any limiting means capable of giving a directional characteristic to the emitted light so that the diverging direction of the light can be limited in a required limiting manner may be applied.

As described above, when the divergence direction of the light emitted from the point light source PSI is limited by the light divergence direction limiting member, the lighting state of the point light source PSI is controlled by the computer, and Within a predetermined range in the three-dimensional space where the eye lens plate FEL exists, the shape of the three-dimensional image to be recorded is displayed as a continuous linear light locus, or When the shape of a three-dimensional image to be recorded is displayed by an arrangement of light spots, the light emitted from the point light source PSI has its diverging direction restricted in a predetermined manner. In a state in which the fly-eye lens plate FEL is incident on each single-lens lens in the fly-eye lens plate FEL, the photosensitive recording member PSM provided on the focal plane of the fly-eye lens plate FEL has the above-mentioned compound eye lens F The image of the point light source PSI is formed for each lens (single lens) within a predetermined range in L, and the photosensitive recording member PSM is disposed so as to be located on the focal plane of the fly-eye lens plate FEL. The image of the point light source PSI in the three-dimensional space in which the fly-eye lens plate FEL exists is formed and recorded in a predetermined number of areas in.

When the lighting position of the point light source PSI moves to a different position in the three-dimensional space where the fly-eye lens plate FEL exists, it is set on the focal plane of the fly-eye lens plate (compound eye lens) FEL. For the photosensitive recording member PSM,
The image of the moved point light source PSI formed for each lens (single lens) in the compound eye lens FEL is
The position is different from the image forming position of the image of the point light source PSI, and the fly-eye lens plate (compound eye lens) FEL
The photosensitive recording member PSM installed on the focal plane of
For each lens (single lens) into which the light from the point light source PSI (light within the angle θ of the light emitted from the point light source PSI) is incident on the compound eye lens FEL described above,
The images of the point light sources PSI are formed and recorded at positions corresponding to the lighting positions of the individual point light sources PSI in the three-dimensional space on the front surface of the fly-eye lens plate FEL, respectively. A fly-eye lens plate FEL is used for the recording member PSM.
The position information of the point light source PSI for each position three-dimensionally displaced in the three-dimensional space where the light exists is recorded, and the fly-eye lens plate (compound eye lens plate) FE is recorded in the recording mode as described above.
The light intensity and position information of the focal point PSI (point light source) shown in FIG. 27 recorded on the photosensitive recording member PSM installed on the focal plane of L, or the virtual focal point PSI ′ shown in FIG. If the photosensitive recording member PSM is of a positive type, the light intensity and the position information are obtained by developing the photosensitive recording member PSM as shown in FIG.
28, only the light intensity and position information of the converging point PSI (point light source) shown in FIG. 28 or the light intensity and position information of the virtual converging point PSI ′ shown in FIG. 28 are transparent and the other portions are black. A recorded photosensitive recording member PSMp developed in such a manner, that is, a recorded photosensitive recording developed in such a manner that only the image portion of the point light source becomes transparent and the other portions become black. The member is PSMp.

The above-described recorded photosensitive recording member PSMp
When the relative positional relationship between the fly-eye lens plate FEL used in recording and the fly-eye lens plate FEL having the same configuration as the fly-eye lens plate FEL is the same as that in the recording, the fly-eye lens plate FEL and the fly-eye lens plate FEL are used. Is a photosensitive recording member PSMp recorded from the opposite side.
When the diffused light is emitted from the light source, the light transmitted through the recorded photosensitive recording member PSMp is condensed for each single-lens on the fly-eye lens plate FEL, so that it can be observed at a position distant therefrom. It is perceived that a point of light exists at the above-mentioned condensed position by a person, but it is possible to observe a reproduced image without a spurious image or a ghost image over a wide viewing area, and Assuming that an image of a point light source at each of a number of positions three-dimensionally displaced in a three-dimensional space is recorded as the recorded photosensitive recording member PSMp, the recorded photosensitive recording member PSM
The image at each position of the point light source recorded in Mp is condensed for each individual eye lens on the fly-eye lens plate FEL, and is collected in the three-dimensional space where the fly-eye lens plate FEL exists. Since a real image is formed at the position of the original point light source in the above, when a person located at a position distant from the position of the real image sees, a line of light or a light line appearing at the position of the real image in the three-dimensional space described above. The whole point can be perceived as a three-dimensional image by light.

In the XYZ plotter described so far with reference to FIGS. 18 to 25, the three-dimensional reproduced image to be drawn in the three-dimensional space by the three-dimensional movement of the point light source is converted into the X-ray CT. By applying the technology, the subject is irradiated with X-rays, the X-rays transmitted through the subject are received by an X-ray detection system, and the subject is obtained by digital calculation based on X-ray projection data from multiple directions obtained. With clear tomographic image data inside,
The point light source of the XYZ plotter is three-dimensionally moved to draw in a three-dimensional space, and the three-dimensional image information is stored in a photosensitive recording member provided on a focal plane of a fly-eye lens plate FEL. The light can be recorded on the PSM, the recorded photosensitive recording member PSMp is irradiated with diffused light from a light source, and the light emitted from the recorded photosensitive recording member PSMp can display a three-dimensional reproduced image in a three-dimensional space. Thus, the three-dimensional reconstructed image drawn in the three-dimensional space makes it possible to easily know, for example, the presence of a tumor or hematoma inside the human brain. When obtaining an image indicating the presence of a glass piece that has entered the human body, image data may be obtained using a magnetic resonance imaging apparatus.

By the way, the range (viewing area) in which the three-dimensional reconstructed image displayed in the three-dimensional space can be correctly observed is narrow as described above, and thus the three-dimensional reproduced image is displayed in the three-dimensional space as described above. It is extremely difficult for the doctor and the patient to explain to the patient while observing the three-dimensional reconstructed image without spurs. In other words, unless the visual field is narrow, for example, unless the doctor and the patient are in an extremely unnatural state in which the face is brought into close contact, both the doctor and the patient together form a three-dimensional reconstructed image without spurs. This is because they cannot be observed. In addition, the physician can explain the three-dimensional reconstructed image displayed in the three-dimensional space using a stick or the like inside the three-dimensional reconstructed image, or use a measuring instrument such as a ruler or caliper to measure the depth. When an object is inserted into the three-dimensional reproduction image, such as when measuring the dimensions in the direction and the dimensions of any part in the three-dimensional reproduction image, for example, to be shielded by the inserted object, A phenomenon such as disappearance of the display of the portion closer to the observer than the insertion position of the object appears which is not experienced in daily life.

Further, for the reasons described above, the fly-eye lens plate F
In the vertical direction of the surface of the recording medium having a structure in which the EL and the two-dimensional photosensitive recording member PSM are integrated, a three-dimensional reproduction image of a real image is displayed in a space in front of the recording medium surface. In order to display a three-dimensional reproduced image by a virtual image in the space behind the surface, three-dimensional image information that can display the three-dimensional reproduced image in both the front and rear spaces of the recording medium surface is used. When the recording is performed on the two-dimensional photosensitive recording member PSM, when the photosensitive recording member PSMp recorded on the recorded recording medium is irradiated with the reproduction light, the photosensitive recording member PSMp is formed in a good state in the three-dimensional space. A recording medium using a fly-eye lens plate FEL having optical performance such that the size of a three-dimensional reproduced image that can be obtained is, for example, 7.5 cm with respect to the vertical dimension of the fly-eye lens plate FEL. Even if it is 15cm in size It is possible to observe the human brain with good quality in a good condition. However, for the three-dimensional reproduction image, a doctor can perform three-dimensional reproduction of a three-dimensional reproduction image based on a virtual image of the space behind the recording medium surface. Use a pointing stick or the like inside the image to explain, or use a measuring instrument such as a ruler or caliper to measure the depth dimension or the dimensions of any part in the 3D reconstructed image. Can not.

The three-dimensional image observation apparatus of the present invention has a recorded two-dimensional photosensitive recording member PSM in which the three-dimensional image information is recorded on the two-dimensional photosensitive recording member PSM installed on the substantially focal plane of the fly-eye lens plate FEL. The photosensitive recording member PSMp is irradiated with reproduction light of diffused light, and the emitted light from the recorded photosensitive recording member PSMp is emitted by a fly-eye lens plate FEL in a direction perpendicular to the surface of the recorded photosensitive recording member PSMp. Regarding the direction, even when a three-dimensional reconstructed image of only the real image is displayed in the space in front of the fly-eye lens plate FEL, or in the direction perpendicular to the surface of the recorded photosensitive recording member PSMp, 3D reconstructed image (Fig. 1)
To the parts indicated by Ir in the drawings of FIGS.
Is displayed, and in the space behind the fly-eye lens plate FEL, a three-dimensional reconstructed image (a portion indicated by reference numeral Iv in FIGS. 1 to 17) by a virtual image is displayed.
Even when the three-dimensional reconstructed image FTD is displayed in both the space in front of and behind the fly-eye lens plate FEL, the three-dimensional reconstructed image can be observed without the above-mentioned problems. 1 to 17 are diagrams showing a schematic configuration of the three-dimensional image observation device of the present invention.

In the three-dimensional image observation apparatus of the present invention shown in FIGS. 1 to 17, the RM is a recording medium having a structure in which a fly-eye lens plate FEL and a two-dimensional photosensitive recording member PSM are integrated. This is a recorded recording medium in which three-dimensional image information is recorded on a one-dimensional photosensitive recording member PSM using, for example, an XYZ plotter having the configuration described above. In implementing the present invention, a fly-eye lens plate FE
L and the two-dimensional photosensitive recording member PSM may be configured separately, but in this case, as described above, the recorded photosensitive recording member PSMp and the fly-eye lens during recording are used. The relative positional relationship between the fly-eye lens plate FEL and the same fly-eye lens plate FEL is determined by the relative position between the fly-eye lens plate FEL and the two-dimensional photosensitive recording member PSM when three-dimensional image information is recorded by the XYZ plotter. It is necessary to set the same as the general positional relationship.

In the drawing symbols shown in each figure,

In the case where the indicator is provided with a fluorescent paint, etc., it is a light source of invisible light (e.g., ultraviolet light) provided as necessary,
FTDi is a reproduction light of diffused light on a recorded photosensitive recording member PSMp in which three-dimensional image information is recorded on a two-dimensional photosensitive recording member PSM installed substantially on a focal plane of a fly-eye lens plate FEL. Irradiates the light emitted from the recorded photosensitive recording member PSMp by the fly-eye lens plate FEL, in correspondence with the three-dimensional reproduced image FTD formed in the three-dimensional space, by the half mirror HM. The virtual image which arises in a position of mirror symmetry is shown.

The recorded photosensitive recording member (PSMp) of the recorded recording medium RM has three-dimensional image information recorded by using an XYZ plotter as described above with reference to FIGS. That is, when the recorded photosensitive recording member (PSMp) of the recorded recording medium RM is irradiated with diffused reproduction light from the three-dimensional image reproducing light source LSr, the fly-eye lens of the recorded recording medium RM is used. Even in the space in front of the plate FEL, even three-dimensional image information capable of displaying a three-dimensional reproduction image using only a real image or recorded using an XYZ plotter as described above with reference to FIG. Three-dimensional image information, that is, recorded recording medium RM
When the recorded photosensitive recording member (PSMp) is irradiated with reproduced light of diffused light from the three-dimensional image reproducing light source LSr,
A three-dimensional reproduced image of a real image is displayed in a space in front of the fly-eye lens plate FEL of the recorded recording medium RM, and a virtual image is formed in a space behind the fly-eye lens plate FEL of the recorded recording medium RM. Three-dimensional image information that can display a three-dimensional reproduced image in both the front and rear spaces of the recording medium surface so that the three-dimensional reproduced image is displayed may be used. In each figure showing the three-dimensional observation device of the present invention,
The recorded photosensitive recording member (PS) of the recorded recording medium RM
When Mp) is irradiated with diffused reproduction light from the three-dimensional image reproduction light source LSr, a three-dimensional reproduction image of the real image Ir is displayed in a space in front of the fly-eye lens plate FEL of the recorded recording medium RM. In addition, an example is shown in which a three-dimensional reproduced image based on the virtual image Iv is displayed in the space behind the fly-eye lens plate FEL of the recorded recording medium RM.

First, in FIG. 1, the recorded recording medium RM irradiated with the reproduction light by the diffused light emitted from the three-dimensional image reproduction light source LSr constituted by using, for example, a fluorescent lamp, a reflecting mirror, and a diffusion plate is used. , Recorded recording medium R
As shown in the three-dimensional reproduced image portion of the real image Ir displayed in the space in front of the fly-eye lens plate FEL of M, and in the space behind the fly-eye lens plate FEL of the recorded recording medium RM. A three-dimensional reconstructed image FTD including both parts of the three-dimensional reconstructed image by the visible virtual image Iv is displayed in a three-dimensional space as shown in FIG. The observer OBS1 shown in FIG.
The TD can be perceived as a three-dimensional image existing in a three-dimensional space. The part of the three-dimensional reconstructed image by the real image Ir in the three-dimensional reconstructed image FTD is formed by reconstructed light being formed in a three-dimensional space. Measuring tool S
It is also possible to actually measure the dimensions of each part inside and outside using CL.

However, in the three-dimensional reproduced image FTD formed in the three-dimensional space as described above, the recorded recording medium R
For the part of the three-dimensional reconstructed image formed by the virtual image Iv that appears to be displayed in the space behind the M-eye fly-eye lens plate FEL, the observer OBS1 actually uses the measuring tool SCL such as a caliper or a ruler. It cannot be measured. Further, even in the part of the three-dimensional reconstructed image by the real image Ir in the three-dimensional reconstructed image FTD, a measuring tool SC such as a vernier caliper or a ruler made of an opaque material is provided inside the part.
When L is inserted, the opaque part inserted in the part of the three-dimensional reproduced image shielded by the insertion of the measuring tool SCL, that is, the part of the three-dimensional reproduced image of the real image Ir in the three-dimensional reproduced image FTD is inserted. The portion closer to the observer OBS1 than the measuring tool SCL such as a vernier caliper and a ruler made of a material disappears because it is shielded by the measuring tool SCL such as a vernier caliper and a ruler made of the opaque material. Therefore, for example, even if an attempt is made to measure the depth dimension of the part of the three-dimensional reproduced image based on the real image Ir in the three-dimensional reproduced image FTD, it may not be possible to measure the depth dimension.

However, in the three-dimensional image observation apparatus of the present invention shown in FIG. 1, a part of a three-dimensional reproduced image based on the real image Ir displayed in the space in front of the fly-eye lens plate FEL of the recorded recording medium RM includes: The above-mentioned tertiary object which is an object to be observed which comprises both a part of a three-dimensional reproduced image by a virtual image Iv which appears to be displayed in the space behind the fly-eye lens plate FEL of the recorded recording medium RM.

Of the three-dimensional reconstructed image FTD composed of both the part of the three-dimensional reconstructed image and the part of the three-dimensional reconstructed image by the measurement tool SCL such as a vernier caliper or ruler held by the observer OBS1. The same result as measured can be obtained.

As described above, in the space where the observer OBS1 is performing the dimension measurement operation using the measuring tool SCL such as a caliper or a ruler, only the observer OBS1 alone reflects the tertiary light by the reflected light from the half mirror HM. Original reproduction image FT
A virtual image FTDi of D is perceived, and it appears as if there is a three-dimensional reconstructed image having a three-dimensional size. However, the one observer OBS1 is a measuring tool such as a caliper or a ruler. Nothing actually exists in the space where the dimension measurement operation is performed using the SCL.

[0100] The above description is based on the recorded recording medium R.
The recorded light-sensitive recording member (PSMp) of M was irradiated with diffused reproduction light from the three-dimensional image reproduction light source LSr, and was displayed in the space in front of the fly-eye lens plate FEL of the recorded recording medium RM. From both the part of the three-dimensional reproduced image by the real image Ir and the part of the three-dimensional reproduced image by the virtual image Iv appearing to be displayed in the space behind the fly-eye lens plate FEL of the recorded recording medium RM. 3D reconstructed image FT
When D is displayed, the three-dimensional reproduced image FT is displayed.
Regarding D, it was impossible to measure the dimensions of the portion of the three-dimensional reconstructed image by the virtual image Iv using a measuring tool SCL such as a caliper and a ruler.
As described above, in the three-dimensional image observation apparatus of the present invention, by using the half mirror HM, it was possible to change the above-described impossible things to possible. The same applies to all embodiments shown for the image observation device.

As described above, the virtual image FTD of the three-dimensional reproduced image
In order to clearly perceive the measurement result when performing an operation of measuring a dimension using an instrument SCL such as a caliper or a scale held by the observer OBS1 with respect to an arbitrary portion of i. In a required portion of the measuring tool SCL such as a vernier caliper or a ruler, a display portion made of a fluorescent paint is provided, and the measuring tool SCL such as the caliper or the ruler described above is irradiated with light from a light source LSb of invisible light (for example, ultraviolet light). It is an effective means to make the display location by the fluorescent paint in (4) bright.

The three-dimensional image observation device described above with reference to FIG. 1 is an example of the configuration of a three-dimensional image observation device in which the half mirror HM is arranged so that the projected area of the mirror surface on the floor is extremely small. However, FIG. 3 shows the half mirror HM so that the projected area of the mirror surface on the floor is extremely large.

Also in the three-dimensional image observation device illustrated in FIG. 3, similarly to the three-dimensional image observation device described above with reference to FIG. 1, the recorded state irradiated with the reproduction light by the diffused light emitted from the three-dimensional image reproduction light source LSr. Recording medium R

By performing an operation of measuring the size of the arbitrary portion of the recording medium RM using a measuring tool SCL such as a caliper or a ruler held by the observer OBS1, the fly-eye lens of the recorded recording medium RM is used. The three-dimensional reproduced image portion of the real image Ir displayed in the space in front of the plate FEL and the virtual image Iv appearing to be displayed in the space behind the fly-eye lens plate FEL of the recorded recording medium RM. Regarding the whole of the three-dimensional reconstructed image FTD including both parts of the reconstructed image and the part thereof,
It is possible to obtain the same results as those measured by the measuring tool SCL such as a caliper or a scale held by the observer OBS1 in his hand.

The three-dimensional reproduced image portion of the real image Ir displayed in the space in front of the fly-eye lens plate FEL of the recorded recording medium RM as described above, and the fly-eye lens of the recorded recording medium RM. Instead of directly observing the three-dimensional reconstructed image FTD composed of both the part of the three-dimensional reconstructed image and the part of the three-dimensional reconstructed image by the virtual image Iv which appears to be displayed in the space behind the plate FEL, When using the HM to observe the virtual image FTDi of the three-dimensional reproduced image that the observer OBS1 can perceive with respect to the three-dimensional reproduced image FTD, the virtual image FTDi of the three-dimensional reproduced image perceived by the observer OBS1 is A three-dimensional reproduction image in a state of a mirror-like relationship with respect to the three-dimensional reproduction image originally observed by the observer OBS1; Alternatively observer OBS1 is possible to observe a three-dimensional reconstructed image of the opposite state for the vertical direction.

For example, when the observer OBS1, the recorded recording medium RM, and the half mirror HM are related to each other as in the configuration example of the three-dimensional image observation apparatus shown in FIG. In the plan view of the state in which OBS1 is viewed from above, the observer OBS1, the recorded recording medium RM, and the half mirror HM are disposed with the upper end surface of the half mirror HM shown in the figure. In this case, the fly-eye lens plate F of the recorded recording medium RM

The three-dimensional reconstructed image FTD including both parts of the image part and the virtual image FTDi of the three-dimensional reconstructed image that can be perceived by the observer OBS1 with respect to the three-dimensional reconstructed image FTD using the half mirror HM, It is upside down.

Also, for example, when the observer OBS1, the recorded recording medium RM, and the half mirror HM are related to each other as in the configuration example of the three-dimensional image observation apparatus shown in FIG. In the side view of the state where the observer OBS1 is viewed from the side, the half mirror HM has the observer OBS1 with the side end face shown in the figure,

A three-dimensional reproduced image FTD composed of both a part of a three-dimensional reproduced image by a virtual image Iv which appears to be displayed in the space behind the fly-eye lens plate FEL of the recorded recording medium RM, and a half mirror The virtual image FTDi of the three-dimensional reproduced image that can be perceived by the observer OBS1 using the HM is opposite to the virtual image FTDi of the three-dimensional reproduced image FTD.

The above problem is caused by the three-dimensional image observation apparatus shown in FIG. 16, for example, in which a total reflection mirror M is provided between a recorded recording medium RM and a half mirror HM. This can be solved by using an image observation apparatus.
7, a three-dimensional image observation apparatus having a configuration in which a total reflection mirror M is provided between a recorded recording medium RM and a half mirror HM as in the three-dimensional image observation apparatus exemplified in FIG. And such a solution is shown in FIGS.
May be applied to the three-dimensional image observation device illustrated in FIG. 1), but the recorded recording medium RM and the half mirror HM are different from the three-dimensional image observation device illustrated in FIGS. Even if the surface total reflection mirror M is not provided between the three-dimensional reproduction image reproduced from the recorded recording medium RM as the three-dimensional image information to be recorded on the recorded recording medium RM, The solution is to record the three-dimensional image information in advance using an XYZ plotter so that the three-dimensional reproduction image is reversed in the horizontal direction or the three-dimensional reproduction image is reversed in the vertical direction. It is needless to say that such a solution can be favorably applied also to the three-dimensional image observation apparatus illustrated in FIGS. 7 to 15.

And a diffusion plate (for example, a sliding glass plate) 4 is provided in a part of the housing 1. The luminous flux emitted from the incandescent lamp 2 with the reflecting mirror is converged by the reflecting mirror and diverges after forming a converging point. The focal point of the luminous flux emitted from the incandescent lamp 2 is located near the area where the open / close light-shielding plate 3b attached to the movable portion of the plunger in the shutter 3 moves in and out of the optical path. When the switch 5 (for example, a foot switch may be used) is turned on and off, the shutter 3 operates to move the open / close light shielding plate 3b into and out of the optical path.

Thus, the reproduction light is on / off controlled.

Then, the light source L for three-dimensional image reproduction described above is used.
The recorded recording medium RM irradiated with the reproduction light by the diffused light emitted from the Srv outputs the three-dimensional reproduced image having the brightness corresponding to the light amount of the reproduction light to the recorded recording medium RM.

However, in practicing the present invention, for example, a dimming device using a thyristor is used. Is also good. The adjustment of the light amount of the reproduction light for irradiating the recorded recording medium RM and the on / off control of the reproduction light are performed in accordance with the difference in the use mode of the three-dimensional image observation device and the indoor illumination lamp (without illuminating the operating table).

The three-dimensional object 8 mounted on the table 9 (or the three-dimensional object 8 mounted on the table 9) may be illuminated by illumination light emitted from a light source (not shown). Particularly, when the three-dimensional object is a human being subjected to surgery, the human 8 on the table 9 is illuminated with a very powerful illumination light by a surgical lamp above at the time of surgery. It is in the state that is being done. By the way, in the three-dimensional image observation device illustrated in FIG. 7, the observer OBS1 has the three-dimensional image reproduction light source L
A three-dimensional reproduced image FTD in which the light emitted from the recorded recording medium RM irradiated with the reproduction light by the diffused light emitted from the Srv is displayed in a three-dimensional space by the fly-eye lens plate FEL of the recorded recording medium RM. Is reflected by the half mirror HM provided in the optical space between the three-dimensional reproduced image FTD and the observer OBS1.
The three-dimensional reproduced image FTD can be observed by the virtual image FTDi perceived by S1.

However, as described above, the relative position between the virtual image FTDi of the three-dimensional reproduction image FTD perceived by the observer OBS1 and the three-dimensional object 8 mounted on the table 9 is adjusted, and The two images are superimposed, and the three-dimensional object on the table 9 and the three-dimensional reproduction image FT perceived by the observer OBS1
In the case where the composite image of the virtual recording medium RM and the virtual image FTDi of D can be observed, for example, the fly-eye lens plate F of the recorded recording medium RM is placed at the position of the human head lying on the operating table 9.
Observer OBS1 shows a three-dimensional reconstructed image showing the state of the inside of the human head displayed in a three-dimensional space by EL.
It is also possible to perform an operation while observing a superimposed composite image such that the virtual image FTDi perceived by the user is located. By the way, as described above, the three-dimensional object 8 and the observer O
When observing a combined image obtained by combining the three-dimensional reproduced image FTD and the virtual image FTDi perceived by the BS1, the observer can recognize a clear combined image of each of the images forming the combined image. Although it must have such brightness, illumination by a surgical light performed on a human on the operating table as in the above-described example is generally a high illuminance. The brightness of the person on the table is high.

As described above, the high-luminance three-dimensional object and the virtual image FTD of the three-dimensional reproduction image FTD perceived by the observer OBS1.
When observing a composite image with i, for example, as described in FIG.
By adjusting the light control device 7 shown therein, the light amount of the reproduction light is increased in accordance with the high luminance of the three-dimensional object, and the luminance of the virtual image FTDi of the three-dimensional reproduction image FTD perceived by the observer OBS1. Is increased so that the two images are recognized by the observer as a clear composite image, or, for example, the three-dimensional reproduction image F perceived by the observer OBS1 is
When observing the composite image of the TD and the virtual image FTDi, the illuminance of the illumination light of the three-dimensional object 8 is reduced by the dimmer 12 or the changeover switch 11 shown in FIG. -Dimensional reproduction image FT perceived by the person OBS1
It is necessary that the composite image of D and the virtual image FTDi can be recognized by a viewer as a clear composite image.

In FIG. 8, reference numeral 10 denotes an illumination light source for a three-dimensional object 8 mounted on a table 9. In the example shown in the figure, the illumination light source 10 includes an incandescent lamp 10a used as a light source for illumination and a reflective light source. It is shown as being constituted by mirror 10b. One end of the incandescent lamp 10a is connected to one terminal of a power source, and the incandescent lamp 10a
The other end is connected to the movable contact v of the changeover switch 11. The switch 11 may be a foot switch. The fixed contact a of the changeover switch 11 is connected to the other terminal of the power supply described above, and the fixed contact b of the changeover switch 11 is connected to the other terminal of the power supply through the dimmer 12. ing. The light control device 12 is shown as using a variable resistor for simplicity in the figure, but a light control device using a thyristor may be used for implementation. When the above-mentioned table 9 is an operating table and the three-dimensional object 8 is a human who undergoes surgery,
Illumination light source 1 for three-dimensional object 8 placed on table 9 described above
Numeral 0 is the operating light described above.

In the three-dimensional image observation apparatus shown in FIG. 8, a part of the three-dimensional object 8 placed on
3D displayed in a 3D space by the 3D image information recorded on the recorded recording medium RM irradiated with the reproduction light of the diffused light emitted from the 3D image reproduction light source LSrv provided therein. With respect to the reproduced image FTD, a virtual image FTDi due to reflected light of the half mirror HM existing at a position mirror-symmetric with respect to the reflection surface of the half mirror HM.
The installation position of the above-mentioned housing 13 so that
In a state where the relative positional relationship with the installation position of the three-dimensional object 8 on the table 9 is determined, the luminance of the three-dimensional object 8 placed on the table 9 and the three-dimensional reproduction image FTD described above
Is appropriate, the observer OB viewing the head of the three-dimensional object 8 (eg, a patient undergoing a brain operation) placed on the table 9 through the half mirror HM.
S1 (doctor) provides a three-dimensional reproduction image F displayed in a three-dimensional space on the head part of the patient who undergoes the above-mentioned brain operation by the three-dimensional image information recorded on the recorded recording medium RM.
A composite image of a state in which a virtual image FTDi due to reflected light of the half mirror HM existing at a mirror-symmetric position with respect to the reflection surface of the half mirror HM overlaps TD (a three-dimensional reconstructed image of the brain of the patient). Is perceived through the opening 13a.

The observer OBS1 (physician) shown in FIG. 8 uses the three-dimensional image information recorded on the recorded recording medium RM, for example, on the head of a patient who is going to undergo a brain operation. With respect to the three-dimensional reconstructed image FTD (the three-dimensional reconstructed image of the patient's brain described above) displayed in the three-dimensional space, the reflection of the half mirror HM existing at a mirror-symmetric position with respect to the reflection surface of the half mirror HM. In order to be able to perceive a synthesized image in a state where the virtual images FTDi by light are superimposed, the luminance of the three-dimensional object 8 placed on the table 9 as described above and the luminance of the three-dimensional reproduction image FTD are described. The relationship with the brightness must be proper,
In order for the relationship between the luminance of the three-dimensional object 8 placed thereon and the luminance of the three-dimensional reproduced image FTD to be in an appropriate state, the dimming device 7 illustrated in FIG. The light amount of the reproduction light is adjusted by using the light source 10 of the three-dimensional object 8 by the light control device 12 illustrated in FIG.

In FIG. 8, when the movable contact v of the changeover switch 11 is switched to the fixed contact a,
The illumination light source 10 of the three-dimensional object 8 is set to be able to illuminate the three-dimensional object with the maximum amount of illumination light, regardless of the dimmer 12, and the movable contact v of the changeover switch 11 is switched to the fixed contact b side. In the state in which the three-dimensional object 8 is illuminated, the illumination light source 10 of the three-dimensional object 8 can be illuminated with the amount of illumination light set in the dimmer 12. For example, the doctor (observer) OBS1 switches the movable contact v of the changeover switch 11 to the fixed contact b side, and, for example, puts the recorded recording medium RM on the head of the patient 8 who is going to undergo a brain operation. With respect to the reflection surface of the half mirror HM with respect to the three-dimensional reproduction image FTD (the three-dimensional reproduction image of the patient's brain) displayed in the three-dimensional space by the three-dimensional image information recorded in After obtaining reference information for surgery by perceiving a composite image in a state in which the virtual image FTDi by the reflected light of the half mirror HM existing in the superimposed state is superimposed, the movable contact v of the changeover switch 11 is changed to the fixed contact a side. In this state, the patient 8 is illuminated with illumination light having an illuminance necessary for the operation, and the doctor OBS1 performs the operation.

If the doctor OBS1 needs the reference information for the operation as described above during the operation, the movable contact v of the changeover switch 11 is switched to the fixed contact b side, and A three-dimensional reconstructed image F displayed in a three-dimensional space by the three-dimensional image information recorded on the recorded recording medium RM on the head of the patient 8 who is about to undergo surgery.
The virtual image FTDi by the reflected light of the half mirror HM existing at a mirror-symmetric position with respect to the reflection surface of the half mirror HM is superimposed on TD (the three-dimensional reconstructed image of the brain of the patient 8 described above). By perceiving the synthesized image to obtain reference information for the operation, the movable contact v of the changeover switch 11 is switched to the fixed contact a side to continue the operation based on the obtained information, and the patient 8 is operated for the operation. If the doctor OBS1 repeats the operation by illuminating with the illumination light of the required illuminance, the operation can be performed easily as compared with the conventional operation.

When the movable contact v of the changeover switch 11 is switched to the fixed contact a side, the three-dimensional object 8 can be operated by the maximum amount of illumination light of the illumination light source 10 for operating the three-dimensional object. Even if it is illuminated, the reproduction light is sufficiently bright, and for example, a three-dimensional image displayed in a three-dimensional space by the three-dimensional image information recorded on the recorded recording medium RM on the head of the patient 8, for example. A virtual image FTDi due to the reflected light of the half mirror HM existing at a mirror-symmetric position with respect to the reflection surface of the half mirror HM is superimposed on the reproduced image FTD (the three-dimensional reproduced image of the brain of the patient 8 described above). If reference information for the operation is obtained by perceiving the composite image of the state, the operation may of course be performed in that state.

As described above, the three-dimensional image reproducing light source LS
When the reproduced light by the diffused light emitted from the rv is sufficiently strong, the half mirror HM existing at a mirror-symmetric position with respect to the reflection surface of the half mirror HM with respect to the three-dimensional reproduced image of the brain of the patient 8. Image FTDi by reflected light of
Although the operation can be continued while sensing the composite image of the superimposed state, during normal operation, the patient 8 is in a state where the patient 8 is illuminated with extremely intense illumination light from the upper surgical light. Therefore, it is difficult to observe a combined image in a state where the virtual image FTDi by the reflected light of the half mirror HM is superimposed on the patient 8 during the operation as described above.

Then, as described above, for example, the three-dimensional reproduced image of the brain of the patient 8 recorded on the recorded recording medium RM, for example, on the head of the patient 8 with respect to the reflection surface of the half mirror HM After perceiving a synthetic image in a state where the virtual images FTDi by the reflected light of the half mirror HM existing at mirror-symmetrical positions are superimposed and obtaining reference information for surgery, the virtual image FTDi disappears enough to disappear. When the patient 8 is illuminated by the illumination light source 10 of the three-dimensional object 8 (patient 8) with bright illumination light, the observer OBS1 cannot recognize the virtual image FTDi described above.
In this case, the half mirror HM existing between the patient 8 and the observer OBS1 becomes harmful enough to cause a loss in the amount of light given to the eyes of the observer OBS1.

FIG. 9 shows a configuration in which the half mirror HM is removed from the optical path between the observer OBS1 and the three-dimensional object 8 when the half mirror HM is made unnecessary as described above. 1 shows a configuration example of a three-dimensional image observation apparatus described above. In FIG. 9, reference numeral 14 denotes a rotation axis of the half mirror HM. The half mirror HM is rotated between two positions, a solid line position and a dotted line position, in a range of an arrow 15 in the figure. It is provided so as to be able to rotate about 14 as a rotation center. The half mirror HM is held at any position between the solid line position and the dotted line position in the figure by an appropriate fastening mechanism. As the fastening mechanism, for example, a member having a metal ball urged resiliently, and a member having a hole engaged with a part of the peripheral surface of the metal ball, A configuration provided in connection with the mirror HM and the housing 13 (not shown) may be used (the above configuration is well known in a click motion mechanism).

In the three-dimensional image observation apparatus illustrated in FIG. 10, when the half mirror HM is made unnecessary as described above, the half mirror HM moves between the observer OBS 1 and the three-dimensional object 8. The entire three-dimensional image observation apparatus is moved to a position indicated by a solid line position and a dotted line position in FIG.
It is configured to be able to move between positions. FIG.
At 0, 16 is a motor, 17 is a member for converting the rotational operation of the motor 16 into a linear displacement, and 18 is a slider for performing a linear motion in the member 17 for converting the rotational operation of the motor 16 into a linear displacement. 10 is a connecting member that couples the housing 13 to the housing 13. When the motor 16 is driven and rotated, the housing 13 moves between a solid line position and a dotted line position in FIG. Can move quickly. Therefore, the whole of the three-dimensional image observation apparatus is shown by a solid line position and a dotted line position in the figure according to when the patient 8 is viewed through the half mirror HM and when the patient 8 is viewed through the half mirror HM. Is moved between these two positions. The member for converting the rotation operation of the motor 16 into a linear displacement is, for example, a slider provided with a female screw engaged with a screw directly connected to the rotation shaft of the motor 16, and a guide rod when the motor 16 rotates. It is possible to use a configuration in which the linear motion is guided by the robot.

As described above, for example, at the position of the head of the person 8 lying on the operating table 9, the above-mentioned three-dimensional space is displayed by the fly-eye lens plate FEL of the recorded recording medium RM. When performing surgery while observing a composite image superimposed such that a virtual image FTDi perceived by the observer OBS1 is located on a three-dimensional reconstructed image showing the state of the inside of the human head, It is necessary that the state of superimposition of the two images is precise,
FIG. 11 shows an example of the configuration of a three-dimensional image observation apparatus capable of satisfactorily superimposing the two images using a positioning marker. The recorded photosensitive recording member PSMp in the recorded recording medium RM shown in FIG. 11 has three or more markers Mk1, Mk
k2 and Mk3 are attached, and three-dimensional image information of the three-dimensional object 8 placed on the table 9 in FIG. 11 is recorded.

That is, in the recorded recording medium RM shown in FIG. 11, three or more alignment marker markers Mk1, Mk2, Mk2, This is a recorded recording medium RM on which three-dimensional image information is recorded with Mk3 (preferably, for example, a metal sphere is used as a marker), and a reproduction light is recorded on the recorded recording medium RM. And a fly-eye lens plate FEL forms a three-dimensional reproduced image FTD in the three-dimensional space, and a half mirror provided in the optical space between the three-dimensional reproduced image FTD and the observer OBS1. The position of the virtual image FTDi of the three-dimensional reconstructed image reflected by the HM and the position of the three-dimensional object 8 are determined by the positioning markers Mk1, Mk2, and Mk.
When the virtual image FTDi of the three-dimensional reproduced image and the three-dimensional object 8 are combined with each other in a state where they are aligned with each other using the three, the inside of the opaque three-dimensional object 8 and the inside of the three-dimensional object 8 are combined. Can be observed as an image in a state where the structure is properly fitted.

For example, if the three-dimensional object 8 is a human head, and the virtual image of the three-dimensional reconstructed image combined with the three-dimensional object 8 is the above-mentioned human brain, the observer OBS1 is assumed to have the brain inside the human head. Can be correctly observed even without cutting the head. Note that the virtual image F of the three-dimensional reproduced image described above
The position where the TDi and the three-dimensional object 8 are combined needs to be separated from the position of the half mirror HM so that the doctor has sufficient space to perform the operation. . Then, using the three or more alignment markers Mk1, Mk2, and Mk3 as described above, the operation of precisely aligning the position of the three-dimensional object 8 with the position of the virtual image FTDi of the three-dimensional reproduced image. Is required to be able to freely displace the housing 13 of the three-dimensional image observation apparatus in multiple directions.

A rotation shaft 31 is provided in a direction orthogonal to the rotation shaft 31, a support member 31 is rotatably fitted to the rotation shaft 30, and 32 is a pin planted in the housing 13. Is rotatably fitted to one end of the support member 31 described above.

The other end of the support member 31 is also connected to the housing 13.
Since the housing 13 of the three-dimensional image observation apparatus is rotatably fitted to the pin implanted in the base, the movement about the rotation axis 22, the movement about the rotation axis 24, and the link 26,
The three degrees of freedom of the position are determined by the movement of 27, the movement about the rotation axis 29, the movement about the rotation axis 30,
The three degrees of freedom of rotation are determined by the movement about the rotation axis 32, and the case 13 of the three-dimensional image observation device is supported by the supporting device having three degrees of freedom in three-dimensional position and rotation. 12 can be freely displaced in the directions of the respective arrows shown in FIG. 12, so that the operation of precisely aligning the position of the three-dimensional object 8 with the position of the virtual image FTDi of the three-dimensional reproduced image can be smoothly performed. . In addition, the base end of the support device described above may be attached to a ceiling or a wall.

Next, the three-dimensional image observation apparatus shown in FIG. 13 to FIG. 15 emits light emitted from the recorded recording medium RM irradiated with reproduction light by diffused light emitted from the three-dimensional image reproduction light source LSrv. A three-dimensional reproduced image FTD displayed in a three-dimensional space by the fly-eye lens plate FEL of the recorded recording medium RM is provided in the optical space between the three-dimensional reproduced image FTD and the observer OBS1. A virtual image FTDi perceived by the observer OBS1 by the reflected light of a certain half mirror HM enables observation of a favorable three-dimensional reproduced image without spurious or the like when observing the aforementioned three-dimensional reproduced image FTD.

In the three-dimensional image observation apparatus shown in FIG. 15, the member 33 provided with the through hole W is provided with a half mirror HM. This is a configuration mode provided between the HM and the recorded recording medium RM.

[0140]

As apparent from the above description, the three-dimensional image observation apparatus of the present invention irradiates a recorded photosensitive recording member on which three-dimensional image information is recorded with reproduction light, The emitted light from the recorded photosensitive recording member is displayed as a three-dimensional reproduced image in a three-dimensional space by a fly-eye lens plate, and the optical space between the three-dimensional reproduced image and the observer is displayed. By observing the virtual image of the three-dimensional reproduction image reflected by the half mirror provided in the inside, or by observing the three-dimensional reproduction image transmitted through the half mirror, the depth dimension and the third order of the three-dimensional reproduction image When measuring the dimensions of any part in the original reconstructed image with a ruler or the like, even if a light-shielding object is put in the three-dimensional reconstructed image, the three-dimensional reconstructed image closer to the observer than the light-shielded object is eliminated Observations and actual measurements A person (for example, a doctor) who observes the three-dimensional reproduced image as a virtual image of the three-dimensional reproduced image reflected by the half mirror, and a person who observes the three-dimensional reproduced image transmitted through the half mirror ( Patient) can observe three-dimensional images in a state without distortion such as spurs at the same time, even if the two patients and the patient observe the opposite image of the left-right (or up-down) relationship.

For example, if the three-dimensional object is a human head and the virtual image of the three-dimensional reconstructed image combined with the human brain is the human brain, the observer can observe the human image of the human. It is possible to observe the state of the brain in the head even without opening the head, and if the human head is combined with a virtual image of a three-dimensional reconstructed image of the human brain and displayed as described above. , Observers accurately perceive the state of the brain in the human head In addition to being able to easily perform brain surgery in a state where it has been done, surgery on a patient in which many pieces of glass are pierced, for example, in a car accident, etc., can also be performed with a tertiary indicating the position of the pieces of glass inside the body. This can be done very easily by combining the original image with the corresponding part of the patient's body.

By providing between the recording medium and the recording medium, it is possible to obtain a three-dimensional reconstructed image without spurious and the like, and the three-dimensional image observation apparatus described above has three degrees of freedom for three-dimensional position and rotation. When the virtual image of the three-dimensional reconstructed image and the three-dimensional object are combined and observed, the internal structure of the three-dimensional object is formed inside the opaque three-dimensional object. It is easy to observe as an image in a well-fitted state, and furthermore, in an opaque three-dimensional object, the structure inside the three-dimensional object can be observed as an image in a well-fitted state. When a virtual image of a three-dimensional reconstructed image and a three-dimensional object are combined and observed, a virtual image of the three-dimensional reconstructed image is controlled by controlling the light intensity of the reproduction light and the light intensity of the illumination of the three-dimensional object, Observation in a state where the three-dimensional object is synthesized can be easily performed, and a virtual image of a three-dimensional reproduced image and a A state that allows easy observation in a state where the original object is combined The light intensity of the reproduction light, the light intensity of the illumination of the three-dimensional object, and the like are set in advance, and the reproduction light is controlled to be turned on and off, or the light intensity of the illumination of the three-dimensional object is set as described above.

Can be easily switched to the state in which is observed, and according to the three-dimensional image observation device of the present invention,
The above-mentioned conventional problems can be solved well and can be effectively used in various applications in many fields of use.
