Description

[Detailed description of the invention]

The present invention relates to data display, storage and processing, and more particularly to a method of recording images on photosensitive materials. There are many domestic and scientific applications that require visual recording, such as photography, cinematography, devision, porography, and copying. Other applications relate to the processing of optical data outside the scope, such as automatic processing of data represented as images on optical displays, transmission and reception of images of small distant objects on large screens, selection of broadcast channels, transmission of holographic movies and television images, etc. 2. Description of the Related Art Methods of recording images on photographic and motion picture films in which silver halide, on which light acts photochemically, is dispersed are known. This method uses expensive materials such as silver and requires lengthy processing of the recorded footage to develop and fix it, erasing the fixed footage and creating new Images cannot be recorded in the same location. It is also known to record images on ceramic plates made of compounds of Pb, Zn, La and Ti. This method uses electro-optic interaction of light with an electrically polarized ceramic plate. This method requires no silver, has a short processing time, and can erase previously recorded footage and record new footage in the same location. However, this method has complicated processing steps, low sensitivity to light, short retention time of recorded images, short image recording-erase cycle, and cannot obtain color images. There are drawbacks such as: Recording an image on a photosensitive material, which involves forming a layer of photosensitive material and placing it in an energy field, and projecting an image of the object to be recorded onto the layer and fixing the image. There are also known methods. Images can be recorded using the magnetic hysteresis effect in magnetic film. The magnetic state of a ferromagnetic material, expressed by parameters such as the magnetic domain structure and the orientation of the magnetization vector with respect to a certain axis of the crystal, is related to the temperature to which the ferromagnetic material has been subjected. A method that utilizes this phenomenon is called thermomagnetic recording. Imaging is performed by a laser beam that uses light obtained from the object being recorded to heat the desired portion of the film to the Curie temperature. The image is then fixed by lowering the temperature of the film by tens or hundreds of degrees. 'The magnetic state of the film changes with the values of Faraday and Cotton-Mouton magneto-optical effects in the case of the M Ship i film, or with the position of the magnetic colloid attached to the film surface in the case of the FeNi film. You can use it to view recorded images. This method has very low sensitivity and requires a minimum optical density of 1 pW/. Furthermore, due to the low magneto-optical properties of the materials used, the light utilization rate for image observation is extremely low (10-5 to 10-
6). As a result, only very sensitive photodetectors can be used to observe the images. This method can only record one basic part of the video at one time, rather than the entire video. Furthermore, since no heat is accumulated even if the light is irradiated for a long time, a lower limit has to be set for the permissible luminous flux. Because the temperature of the magnetic phase transition is high (100° C.) and the thermal conductivity of the magnetic film material is also high, the above lower limit is significantly stricter. It is an object of the present invention to record images of an object in a desired region of the spectral range of the object's direct waves or the object's reflected waves, including the acoustic waves, radio frequency band, visible light band and X-ray band. The purpose of this invention is to provide a method for recording images on materials that can be perceived as such. A second object of the invention is to provide a method for recording images of arbitrary objects in a silver halide-free layer.
A third object of the present invention is to obtain a blurred image that does not require additional processing. A fourth object of the present invention is to visually read recorded images. A fifth object of the present invention is to increase the sensitivity and contrast of substances that are sensitive to radiation, and to obtain good image replacement performance. A sixth object of the invention is to generate color images. A seventh object of the present invention is to enable copying in a bright room. An eighth object of the present invention is to increase the brightness of the generated image. According to the invention, forming a layer of radiation-sensitive material, placing this layer in an energy field, and projecting an image of the object to be recorded onto the layer,
A method of recording an image on a radiation-sensitive material, the method comprising the step of fixing the projected image, using a heterogeneous mixture of materials as the radiation-sensitive material, One component substance is used as a solvent, the component substance can change the state of aggregation in the mixture under the action of direct waves or reflected waves from the object being recorded, and the other component substance can change the state of aggregation of particles. exists in a heterogeneous mixture and can interact with the energy field, projecting an image using direct waves or reflected waves from the object to be recorded, and the projected image acts as a solvent for the heterogeneous mixture. A method of recording an image on a substance related to radiation, which is fixed by converting the state of a set of component substances, is obtained. Before or at the time of recording the image, the layer of the heterogeneous mixture of substances may be heated or cooled to near a temperature at which the substance acting as a solvent changes its state of assembly. An energy absorbing material whose radiation energy/thermal energy conversion rate is greater than the radiation energy/thermal energy conversion rate of other component substances in the heterogeneous mixture and which can interact with an energy field. It is advantageous to add it to the heterogeneous mixture before forming the layer and then to attach it to particles that can interact with the energy field. At least one type of radiation having a radiation energy/thermal energy conversion rate higher than that of other substances present in the heterogeneous mixture and capable of interacting with the energy field. A layer of absorption-absorbing material is formed, and this layer is placed either above or below a layer of inhomogeneous material relative to the material to be recorded. It is preferable to use an optically active material as the radiation absorbing material, and to form a layer using a plurality of microcapsules filled with the optically active material. Radiation-absorbing materials are photoconductive materials, and it is advantageous to place a layer of this material on top of a layer of a heterogeneous mixture. A layer of photoconductive material is placed below the layer of the heterogeneous mixture, and after the image is fixed, the layer of the heterogeneous mixture is further exposed to light. It is advantageous if the microcapsules are made of minimally monochromatic material. During video recording, radiation band colors corresponding to the colors of the recorded object may be discriminated and reproduced in a layer of a heterogeneous mixture. Before or after fixing the projected image, the projected image is further exposed to radiation with a higher intensity compared to that obtained during image recording. The wavelength of the radiation used in this further exposure is selected so that the radiation can pass through the heterogeneous mixture without being absorbed by the mixture. If another exposure is taken before image fixation and the same radiation wavelength is used for image recording and another exposure, then the radiation intensity available during the other exposure time is equal to the radiation intensity available during image recording. It is best to shorten the length by a multiple that exceeds the available radiation strength. The radiation-sensitive material consists of a heterogeneous mixture containing paraffin and iron oxide particles, said paraffin acting as a solvent and melting under the action of direct radiation or reflected radiation from the object being recorded. The energy field is a magnetic field that interacts with iron oxide particles, and is formed by forming a layer using a heterogeneous material on a transparent substrate and by radiation reflected from the object. Advantageously, the projected image is projected onto the layer and the projected image is fixed by cooling the paraffin. The method of the present invention for recording images on radiation-sensitive materials covers the spectral range of direct radiation of an object or reflected radiation of an object, including sound waves, radio frequency bands, visible light bands and X-ray bands. It records an image of an object in a desired area. Images of any object can be recorded on a layer that does not contain silver halide. It is possible to obtain a positive image that requires no further processing, and it is possible to optically discuss the recorded image.
Furthermore, you can make copies in a bright room. This method has high sensitivity and can obtain images with high contrast, as well as good image conversion performance of substances sensitive to radiation. Color images can be generated by the method of the invention, and the brightness of the generated images can be increased during recording. The method of the present invention for recording an image on a radiation-sensitive material includes forming a layer of radiation-sensitive material comprising a heterogeneous mixture of materials. One of the component substances of the heterogeneous mixture acts as a solvent and can change its state of assembly under the action of direct or reflected radiation obtained from the object to be recorded. Other component substances in the heterogeneous mixture are in the form of particles and can interact with the energy field. There are embodiments that deal with a variety of materials that function as solvents and particles, respectively. A layer of a heterogeneous mixture is placed in an energy field and the recorded image of the object is projected onto the layer using direct radiation or reflected waves of the object. The projected image is fixed by transforming the state of the mass of matter that acts as a solvent for the heterogeneous mixture. If an image is fixed by melting the solvent, the recorded image is fixed by cooling the solvent to or below its crystallization temperature. When an image is recorded by sublimating a solvent, the recorded image is fixed by cooling the solvent to or below its sublimation temperature. To reduce power consumption during recording, the layer of the heterogeneous mixture is heated or cooled before or during recording of the image to a temperature that maintains the state of the mass of substances acting as a solvent. To further reduce power consumption during recording, the radiation energy of other substances contained in the heterogeneous mixture /
A radiation absorbing material having a radiation/thermal energy conversion rate greater than the thermal energy conversion rate and capable of interacting with the energy field is added to the heterogeneous mixture before forming the layer of the heterogeneous mixture. , attached to particles that can interact with energy fields. In order to achieve the said objective, the material has a radiation energy/thermal energy conversion rate that is greater than the radiation energy/thermal energy conversion rate of other substances present in the heterogeneous mixture, and the energy field At least one radiation absorbing material capable of interacting with the material is used to form a layer, and the layer is placed above or below the layer of the heterogeneous mixture relative to the object to be recorded. Radiation absorbing materials are photochemically active or photoconductive materials. In the case of photochemically active substances, the substances are packed into a plurality of microcapsules arranged in layers. When using a photoconductive substance, a photoconductive plate connected to a power source is employed. The photoconductive plate is placed on top of the layer of heterogeneous mixture. In order to increase the contrast of the recorded image, a photoconductive plate is placed under the layer of the heterogeneous mixture and the layer is further exposed after the image has been fixed. To obtain color images, microcapsules are made from monochromatic materials. For this purpose, a light filter with non-uniform spatial characteristics is used. This filter is used to distinguish radiation band colors corresponding to the colors of the object being recorded, and to reproduce those band colors when recording an image on a layer of inhomogeneous material. To rewrite the generated image, the brightness of the generated image is increased during or after image recording so as to further expose the image to light before or after fixing the generated image. In this case, the intensity of the further exposure is greater than that available during recording of the image. The wavelength of the radiation used in the further exposure is chosen so that the radiation can pass through the layer of the heterogeneous mixture without being absorbed. Assuming that further exposure is performed before fixing the image, and that the radiation wavelength used for image recording and the further exposure is the same, the exposure time of the further exposure is the same as that used for the further exposure. The video recording time is reduced in proportion to the multiple by which the radiation strength exceeds the radiation strength used during video recording.
In order to be able to better understand the method of the invention,
I will devise some aspects of a simplified theory of video recording. The method of the invention is based on the fact that the state of aggregation of the solvent of a heterogeneous mixture is changed under the action of radiation from the object to be recorded. This means that a "crystal-liquid" or "crystal-gas" type ensemble transition is occurring. The kinetic coefficient of the solvent has a tendency to vary considerably around these transitions. FIG. 1 is a graph showing how viscosity changes with temperature T. For example, in the case of water and paraffin, △T, = 0.01 to 10qomax/rim,n =
1 pi 5 to 1 bi 6. Such drastic changes in the viscosity of the solvent significantly alter the mobility of the particles of the heterogeneous mixture that are charge carriers or electrical and magnetic dipoles. In addition, the mobility of particles in heterogeneous mixtures that can interact with energy fields that move particles in a certain direction, such as electric fields, magnetic fields, and gravitational fields, is also affected by changes in the viscosity of the solvent. If the particles are transparent and the solvent is opaque, the irradiated area of the layer will be more transparent. If the particles are transparent but have a refractive index different from that of the solvent, the overall refractive index of the irradiated part of the layer changes.The equations used to calculate the properties of the method of the invention are then First, assume that the particle is a sphere with radius a. The scale image force R is determined by the following formula: R = hearing brush

The time depends on the viscosity of the solvent and the energy expended by the particles interacting with the external energy field. Assume that this time is shorter than the time t. Therefore, the time required for video recording is determined from the current time L'. These values are related to each other in the case of heterogeneous mixtures as shown by the following equation: Shiichi t3=・Raashi Z

The energy W consumed during video recording is determined by w = Science '61. where p is the radiation power absorbed by the spherical particles and S is the irradiated area of the layer of the heterogeneous mixture. The relationship between the radiation power p in the case of spherical particle absorption and the temperature at which the solvent is heated during time t3 is determined by the point K2ΔTO. Here, r is the distance from the center of the sphere, and △To is the temperature increment (British Journal of Applied Physics (BritishJouM1of, Ap

The reason is that the changes do not have a very large effect on the results obtained. The radiation energy required from the object to record an image is reduced by adding photoconductive or photochemically active substances to the heterogeneous mixture. When the portion of the layer containing these substances is irradiated with radiation,
The energy relationship is determined by the following formula. W is the density of energy generated during irradiation of a photoconductor connected to a power supply or by the interaction of photochemically active substances. be.

G=Nakazume; ≦Difference-Blue Good-Poison (・7) Hereinafter, embodiments of the present invention will be described with reference to the drawings. Example 1 A heterogeneous mixture is prepared as follows. Paraffin 1 (secondary) acts as a solvent for the heterogeneous mixture
(Fig.) and iron oxide fine particles 2 are mixed. These iron oxide particles can absorb almost all of the incident light. This heterogeneous mixture is deposited on the glass substrate 3 in a layer 20-30 microns thick. A glass plate 4 is placed over this layer. This entire assembly is then placed near an external heating source 5. Due to the use of oxide particles 2, the layer formed is practically opaque. The energy field is a magnetic field with a direction perpendicular to the surface of the layer. An image of the object is projected onto the layer. Light L (Figure 3) is emitted from this object toward the layer. More heat is given to the particles 2 present in the parts of the layer that receive more light, and more heat is incident on the parts where more heat is generated. When the particles 2 are heated, the paraffin 1 surrounding those particles is also heated by the heat. When the temperature of the paraffin 1 exceeds its melting point, the viscosity of the paraffin decreases and the position of the particles 2 affected by the magnetic field changes. Particles 2, which are present in the most heated part of the layer, completely change their position,
It becomes a long thin string 6 parallel to the direction of the magnetic field. As a result, the area becomes almost completely transparent. The reason is,
This is because the light scattering area occupied by the particles 2 is reduced and the thin layer of paraffin 1 transmits almost all of the light incident on it. On the other hand, there is a small amount of light present in the area where light is incident, and therefore the amount of heat generated is small, and the transparency of the layer containing particles 2 is low. The image is then fixed within the layer by cooling the layer below the freezing point of the paraffin. As a result, a completed positive image is generated in a layer of a heterogeneous mixture of paraffin 1 and iron oxide particles 2.
Example 2 The procedure in Example 1 is carried out using ice as the solvent for the heterogeneous mixture and a freezing source instead of the heating source 5 of Example 1. In this example 2, a positive image is generated in a layer of a heterogeneous mixture of ice and iron oxide particles 2. Example 3 The procedure described in Example 1 is carried out using artificial ice as the solvent for the heterogeneous mixture. At normal pressure and temperatures close to 18 qo, this artificial ice can change from solid to gaseous state. Example 4 Paraffin 1 is used as a solvent in a heterogeneous mixture and as particles 2 fine particles of iron oxide are used. The field of energy is the field of gravity. A thin layer of a heterogeneous mixture is formed on the surface of a glass substrate 3, and a glass plate 4 is placed over the layer before being placed near an external heating source 5. This layer is heated to the melting point of paraffin 1 and then subjected to a magnetic field perpendicular to the surface. This forms elongated string-like particle groups 6 extending in a direction perpendicular to the surface of the layer. The layer is then cooled to the freezing point of paraffin or below. The layer is then effectively transparent. When an image of the object is then projected onto the surface of the layer, the particles 2 in the layer 2 are heated non-uniformly. Particle 2 included in the part that receives more light generates more heat,
The heat is transferred to the surrounding paraffin 1 and paraffin 1
When the paraffin 1 is heated and the temperature of the paraffin 1 becomes higher than its melting point, the viscosity of the paraffin 1 decreases, allowing the particles 2 under the action of gravity to change their position.
Convection occurs inside liquid paraffin. As a result, the string-like particles 2 are broken in the part of the layer that is heated most intensely and are arranged in pieces in the paraffin. Parts of that layer are therefore opaque. Also, the areas with a small amount of heat generation have low opacity, resulting in half gradation. The negative image is then fixed within the layer by cooling the layer below the freezing point of paraffin 1. Example 5 Paraffin 1 is used as a solvent for a heterogeneous mixture, and as particles 2 opaque microparticles of barium titanate are used. An electric field is applied in a direction perpendicular to the surface of the layer. A thin layer of the heterogeneous mixture is formed on a glass substrate 3 and the layer is covered with a glass plate before being placed near an external heat source 5. The subsequent operations are the same as in Example 1. Example 6 Using paraffin as a solvent in a heterogeneous mixture, particles 2
Fine particles of iron oxide are used as the material. A magnetic field is used as the energy field. Chlorine and hydrogen are used as photochemically active substances. Chlorine and hydrogen are filled into transparent microcapsules 7 made of polyvinyl chloride in a dark room. A layer of a heterogeneous mixture is formed on the surface of the substrate 3. A layer of microcapsules 7 is formed on this layer, and then a glass plate 4 is placed over it. An image of the object is then projected onto the second layer. As a result, an exothermic photochemical reaction occurs in the mixture of chlorine and hydrogen filled in the microcapsule 7, and due to the heat generated,
A portion of the first layer near the illuminated portion of the second layer is heated. When the amount of light incident on the microcapsule 7 is large,
The amount of heat generated also increases, and the temperature of the first layer portion close to the portion generating a large amount of heat becomes higher than other portions. The operations performed thereafter are the same as those described in Examples 1-3. After fixing the image, the two layers are illuminated such that the temperature at which photochemical reactions occur in the second layer can maintain the temperature of the heterogeneous mixture below the melting point of the solvent. Example 7 Microcapsules 8 (FIG. 5) are filled with a photochemical substance and a heterogeneous mixture and the operations described in the example are carried out. Example 8 A heterogeneous mixture is made using 1 part of paraffin and 2 parts of iron oxide fine particles. The energy field is a magnetic field. A thin plate 9 made of Cds+Cu light guide mirror is used as a photoconductive substance. This plate 9 is inserted between transparent electrodes 10. These electrodes 10 are made of indium oxide and are connected to a power source 11. An image of the object is projected onto a board 9. Photoconductive plate 9 receiving light
electrical resistance decreases. The heat generated in the irradiated area heats the heterogeneous mixture layer near that area. Areas that receive a lot of light generate a lot of heat,
Therefore, the temperature of the heterogeneous mixture heated by the heat increases. The subsequent operations are then the same as described in Examples 1-3. Example 9 A similar operation as described in Example 8 is carried out, but the image to be of high contrast is previously recorded in a layer of a heterogeneous mixture. An external light source is used to illuminate the layer of the heterogeneous mixture, avoiding exposure to the sides of the photoconductor plate 9 (FIG. 7). Figure 7 shows the contrast of the recorded video using curve 1.
2. When a layer of a heterogeneous mixture is uniformly irradiated with light L from an external light source, the light incident on the light guide plate 9 is related to the transparency of that layer. The greater the transparency of a given portion of the heterogeneous mixture, the greater the amount of light reaching the photoconductor plate 9. The heat generated in the illuminated portion of the light guiding body plate 9 heats the portion of the heterogeneous mixture layer near that portion. Therefore, the temperature of the more transparent parts of the layer of the heterogeneous mixture will be higher. The subsequent operations are performed in the same manner as described in Examples 1 to 3, and the contrast of the recorded images is increased. When an external light source non-uniformly illuminates the layer of the heterogeneous mixture, the contrast of the recorded image can be increased or decreased according to the operations described above. Example 10 Paraffin 1 is used as a solvent in a heterogeneous mixture and particles 2 are acicular iron oxide particles. A field with one energy is a magnetic field. When carbon black is attached to the surface of the particles 2, the light absorption ability increases. The subsequent operations are the same as those described in Examples 1-4 and 9. Example 11 All operations described in Examples 1 to 10 are performed in this example, but
A light filter having non-uniform spatial properties is provided over the layer of the heterogeneous mixture. The light filter is made as a layer of plexiglass particles with cross-sectional dimensions of less than 10 microns. Each particle is colored red, green or blue. Each particle is placed in closer contact with the transparent substrate and acts as a single area light filter during projection and viewing of the generated image.
These particles are so small that they are invisible to the eye. Because these particles are arranged in a non-uniform manner, after the light that passes through a filter made of these particles is processed by the eye, the filter appears gray. The small gaps between the particles are filled with a transparent adhesive, and an image of the object is projected onto a light filter. For example, in the case of a red object, the light emitted from the object passes through only the red particles and is absorbed by the green and blue particles. As a result, images are recorded only in those portions of the layer of the heterogeneous mixture that receive light transmitted through the red particles of the filter.
The subsequent operations are the same as those described in Examples 1-10. When the generated image is viewed from the side of the optical filter, the image appears red. In this way, the image accurately represents the shape and color of the object and does not require any further processing. Example 12 The operations described in Example 11 are carried out in this example, but in Example 12 microcapsules 8 made of polyvinyl chloride and colored in one primary color, or transparent microcapsules 8 encapsulated with a pigment, are prepared. Thin walls can be used as light filters. These microcapsules are mixed non-uniformly and then arranged in a single layer on a transparent substrate 3 in close contact with each other. Each microcapsule 8 contains a heterogeneous mixture. Example 13 In this example, the operations described in Examples 1, 2, 5, 8, 10, 11, and 12 are performed. An external magnetic field source is provided near the layer of the heterogeneous mixture that generates a variable magnetic field in a direction parallel to the surface of the layer. In another embodiment, the layer is formed over a piezoelectric transducer 13 that is connected to an ultrasound oscillator 14. After recording the image, the layer of the heterogeneous mixture is heated to the melting point of paraffin 1 to fix the image, and the magnetic field perpendicular to the surface of the layer is removed. Then, a variable magnetic field is applied or the ultrasonic oscillator 14 is operated. In either case, the particles in the mixture mix and the image disappears, leaving the layer of heterogeneous mixture ready to record a new image.
Example 14 Perform the operations described in Examples 1, 2, 5, 8, 10, and 11. In addition, a bright light source is provided near the layer of the heterogeneous mixture, and the image obtained from the end of the light guide 15 is transmitted through the lens 16.
to that layer. The images are examples 1, 2, 5, 8
, 10. The image is then briefly illuminated with light from a bright light source, providing a greater illuminance at the surface of the layer than is obtained during image recording. In this case, the image is rewritten to another layer with increased brightness. The end faces of other light guides are sent to transmit the image with such increased brightness elsewhere or to be displayed on a screen. After the image has been transferred, it is erased from the heterogeneous mixture layer in the manner described in Example 13 and the new image sent by light guide 15 is recorded. Images with enhanced brightness can be sent in real time without changing contrast, half-gradation, or color. Transmission of an image through a light pipe is accompanied by attenuation of the light due to scattering that occurs in the light pipe and distortion of the multimode image. To compensate for this distortion, a correction filter made as a plate with special lines is used. This correction filter gives reverse rotation to the image (LEEE, Leith (1977
(January issue) (see pages 18-28). The shape of the lines making up the filter is determined using the known scattering properties of the light guide. If the image is to be amplified and the distortions of the image due to the transmission in the light guide are to be corrected, a correction filter is provided behind the substrate on which the layer of the inhomogeneous mixture is formed. Example 15 Perform the operations described in Example 14. A brightened image is delivered to the screen at a viewable magnification. This has the following uses: Television transmission and reception of images that change over time and do not require conversion to or from electrical signals, reception and optical processing of images that change over time on a display, observation using a normal microscope transmission and reception of images of small objects that are displayed on a large screen; transmission and reception of images of distant objects with increased brightness when viewed through binoculars and astronomical telescopes; Example 16 Perform the operations performed in Example 14. When the brightness-enhanced image is projected onto a screen through a magnifier, such as a diffraction grating, multiple copies of the original image are reproduced at various locations on the screen. Since images of various objects are pre-recorded on the screen, it is possible to recognize stationary patterns using a follow-up correlation comparison method. This means that the condition in which the transmitted brightness-enhanced image matches one of the images on the screen is discriminated (J. Gbodman, ``Introduction to Fourier Optics'').

Example 17 The operation described in Example 14 is performed, but in this case a hologram of the object is sent instead of an image of the object. High brightness holograms are converted into three-dimensional images using known hologram reconstruction methods (see Goodman, supra). The simplified theory described above is a means of approximately evaluating the properties of the method of the present invention for recording images on radiation-sensitive materials.

tt)). The maximum number of image elements is 4, area S = 10-8 = 1
．． It becomes 8×1 piton. This means that the energy required for video recording is reduced by a factor of 100 or less. The photochemically active substances are chlorine and hydrogen, which are encapsulated under pressure in microcapsules. Assuming that the absorption of radiation by these substances follows Beher's law, the following relationship is obtained: P skin Q = Qo ears. Here, Qo is the absorption rate at normal pressure Po. The outside parameters of those substances are as follows. y=1, ΔH=4.5×1 pcal/mol, Q. =
Assuming that P/Po=1, the size of the microcapsule is 1=10-3, and the radiation wavelength is 3×10-5. Substituting these values into equation (13) yields z=1. This means that the energy required for video recording is reduced by a factor of 1,
J/ means to become earth. The brightness increase coefficient of the image when the image is rewritten by further flashing is calculated as follows. Assuming that the radiation of the further exposure is not absorbed by the heterogeneous mixture, the brightness multiplication factor given by equation (15) is related only to the power of the light source using the exposure, and increases as the power increases. can. If radiation emitted during further exposure is assumed to be absorbed by the heterogeneous mixture, the magnitude of the brightness enhancement factor is limited. For example, in the case of television transmission the relevant parameters are: D=1pi, t3=5×10-2
By substituting these values into equation (17) together with to: 5×10-5 seconds, G=1 time can be obtained.
