DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical information processing apparatus capable of performing parallel and distributed high-speed processing of two-dimensional parallel data represented by image information and the like.

[0002]

2. Description of the Related Art An optical information processing apparatus processes, for example, two-dimensional parallel data at high speed by utilizing spatial parallelism, time multiplexing, wavelength multiplexing, and mutual non-interference of light. Until now, various architectures and algorithms have been proposed corresponding to the intended functions and the like.

[0003] Conventional basic configurations for realizing them are as follows: a required array of light emitting elements, an array of light receiving elements, an array of optical switching elements, an array of optical modulators, or a spatial light modulator. A so-called parallel type electro-optical function element such as an optical modulator is mainly mounted on an optical
It is intended to realize some information processing function by exchanging optical information by coupling through a so-called bulk type optical element such as a beam splitter and a mirror.

That is, an optical system of an optical information processing apparatus is configured on the basis of a general optical technology from the past.

On the other hand, the conventional optical technology was developed,
An optical system configuration technology suitable for an optical information processing device has also been proposed.

The following are three examples. The first example relates to a technique using planar optics (J. Jahns).
et. al. , Applied Optics 2
8, 1602 (1989)).

This is one of the major weaknesses of the conventional optical technology, which is to facilitate optical position adjustment and to reduce the size and stability of the optical system.

More specifically, a flat optical element such as a holographic element, a grating or a Fresnel lens is formed on the surface of a glass substrate, and the optical system is folded by utilizing the total reflection of light on the surface of the glass substrate. It is bent and trapped in a glass plate.

The second example is a proposal which also facilitates optical position adjustment and stabilizes an optical system (K. Hmanaka, 1991 Optical C).

Technical Digest Series V
olume 6 (Salt Lake City 19
91), p32.

[0010] This is to provide an optical information processing apparatus in which a flat type active element can be inserted in a confocal plane or a Fourier transform plane of a rod-shaped Selfoc lens, and optical adjustment is easy. is there. This configuration is considered to be effective for optical interconnection between boards.

A third example is a proposal for configuring the entire optical system with a primary focus on miniaturization and stabilization of the optical system (K.
Iga et. al. , Applied Optical
s21, 3456 (1982)).

This is to realize a small-sized optical information processing apparatus by laminating a micro-optical element or a light-emitting element array formed in an array such as a surface emitting laser, a flat microlens array, or the like.

[0013]

The conventional general optical technology on the optical surface plate does not originally correspond to the optical information processing technology which is currently being developed. For a demonstration of the architecture and algorithms,
Although it can be used relatively easily, it is extremely difficult to apply it as a practical and stable system.

In addition, it is necessary to design completely different individual designs depending on the functions to be realized. The combination of the so-called parallel type electro-optical function element and the bulk type optical element, or the overall configuration, depends on the function to be realized. As a result, the optical system was completely different, and a configuration of an optical system having uniformity could not be obtained.

[0015] Therefore, as long as it relies on the technology of forming the optical system by the conventional general optical technology, it is difficult to industrially produce the optical information processing device, and a unified design guideline is established. It is also difficult to do.

The reason for this is that, as described above, the conventional general optical technology does not correspond at all to the developing optical information processing technology. It is in a situation that could hinder development.

At present, there is a demand for a general-purpose, scalable basic optical system construction technology that is exactly compatible with the optical information processing technology, that is, an optical system construction technology that is a new base for the optical information processing technology. I have.

The following three points can be cited as main items required for a new basic optical system construction technology. (1) The optical position can be easily adjusted and the optical system has excellent mechanical stability. (2) An unified optical system with scalable basic components at the core. (3) Even if small and high-density integration is performed, heat generation and heat storage from elements do not pose a problem.

First, from the viewpoint of (1), three major problems of the prior art will be described in detail below.

First, since the parallel electro-optical function elements are connected via the lens system, the position between the parallel electro-optical function elements and the bulk optical elements such as lenses, beam splitters, mirrors, etc. It is required that the relationship be adjusted very precisely.

The first problem will be described in detail below with reference to FIG. 18 by taking an example in which two parallel electro-optical function elements are connected via a lens.

In FIG. 18, reference numeral 41 denotes a parallel type electro-optical function element, and reference numeral 42 denotes a lens. As shown in this figure, in addition to the three directions of up and down, left and right, front and back,
There are six degrees of freedom to adjust in two directions of tilt and rotation.

In the case of a conventional optical information processing apparatus in which a plurality of parallel-type electro-optical function elements and a bulk-type optical element are organically and intricately connected, if their relative positions are not precisely adjusted. In some cases, not only the information processing characteristics are deteriorated, but also the information processing function is lost as a whole.

In a conventional optical information processing apparatus having an advanced information processing function, a position related to six degrees of freedom between a parallel type electro-optical element and a bulk type optical element, which is indispensable for sufficiently exhibiting the function. The adjustment is extremely complicated, and it has been extremely difficult to produce an optical information processing device having a high level of function industrially.

Second, since the parallel type electro-optical function element and the bulk type optical element are arranged discretely, it is difficult to reduce the size of the entire apparatus. Furthermore, since they are arranged discretely, their relative positional relationship is extremely unstable with respect to vibration and environmental temperature, and fluctuates easily. In other words, while securing the aperture on the light input / output surface,
It is very difficult to reduce the size of a parallel type electro-optical function element or a bulk type optical element while maintaining mechanical stability.

Third, even if the first and second problems are solved, a position adjustment can be easily performed, and a method that can stably maintain the position can be obtained, the light carrying the two-dimensional information can be used. Since the light propagates through the normal free space filled with air between the parallel-type electro-optical function elements via the bulk-type optical element, the air flow in the apparatus due to the vibration of the entire optical information processing apparatus or a change in environmental temperature or There is a problem of being affected by the disturbance.

Further, the proposals of the above-mentioned three examples newly designed to be suitable for an optical information processing apparatus, which are exemplified in the prior art, have the following problems, respectively, and are not complete. .

First, a technique using planar optics is excellent in that the optical position adjustment is easy, but not sufficient in terms of expandability.

Since this optical system is basically two-dimensionally spread, when realizing a large-scale and complicated optical information processing apparatus, the optical system is somewhat thin but consumes a large area. Maybe.

It can be said that this proposal is an effective idea as at least a part of a new basic optical component, rather than a basic configuration for a new optical component technology suitable for optical information processing.

Next, the proposal of the optical system using the selfoc lens is excellent in that the optical position can be easily adjusted.

However, the effective diameter of the SELFOC lens is
For example, it has a disadvantage that it is difficult to obtain a large size of several tens of millimeters. Furthermore, there is no specific proposal for basic components that are the core of the information processing device.

A system in which surface-emitting lasers and micro-optical arrays are stacked is considered to be a configuration that can easily realize information processing utilizing parallelism of light, and can achieve miniaturization and mechanical stability. Attractive as a system.

However, the illustrated proposal merely claims that the optical information processing apparatus is actually stacked, and the optical information processing apparatus can be actually realized by any specific method and configuration. That is not mentioned at all. Also, there is no consideration on how to avoid large heat generation and heat storage generated from a high-density integrated surface emitting laser.

The present invention is intended to solve the above problems of the prior art, in particular easy positional adjustment between the mutually parallel electrooptical functional element, the relative position between the parallel electrooptical functional element children Ya vibration An optical information processing device that is less susceptible to environmental temperature fluctuations and further eliminates the influence of air from the optical path,
By providing scalable basic components suitable for optical information processing technology that constitutes a practical optical information processing device with various functions, and optical system configuration technology based on unified guidelines centered on it Another object of the present invention is to provide an extremely practical optical information processing apparatus that can be easily designed based on industrial production and a unified guideline.

[0036]

[0040]

According to the above configuration of the present invention, there are only three degrees of freedom to be adjusted, namely, up and down, left and right, and rotation, and the degree of freedom to be adjusted is smaller than that in the case where an image is transmitted by a lens system. Halve.

Further, as long as the relative position between the parallel type optical functional elements such as the spatial light modulator is determined, the parallel movement or rotation of the fiber plate during that has no influence on the information transmission between the parallel type electro-optical functional elements. Also, the fiber plate of the present invention, equivalent to prior art bulk optics, eliminates the need for precise alignment.

Further, since the parallel type electro-optical function element is installed in close contact with the fiber plate, it is easy to stably maintain its relative position.

[0043] This close-laminated arrangement greatly reduces the size, and at the same time, the light carrying two-dimensional information is transmitted between the parallel-type electro-optical function elements almost without propagating in the air through the fiber plate. Therefore, there is no influence of the flow of air in the apparatus or its turbulence.

Further, if the fitting structure is provided in advance on both the parallel type electro-optical function element and the fiber plate, not only the position of the apparatus is automatically adjusted, but also the fluctuation of the relative position can be almost ignored. Suppress.

On the other hand, since the optical writing type spatial light modulator, the light supplying device to the spatial light modulator, and the optical connection element are sequentially laminated and connected via the fiber plate, only
The system does not expand dimensionally,
By combining these basic components, a complex and large-scale optical information processing system is realized with a uniform configuration.

In addition, light having a stable wavelength and light intensity is supplied from an external light source to the readout light supply device, minimizing the generation and accumulation of heat, and also stabilizing the light output intensity and wavelength. Since it is easy to use a light source having high performance, there is no need to consider uniformity between individual devices, which is a problem when using an integrated light emitting device.

Embodiment 1 Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. In the present embodiment, the optical information processing apparatus
The optical element with applicable functions is the fiber plate
The basic components connected to each other using
From the use of fiber plates to concrete configurations
I will clarify.

FIG. 1 and FIG. 2 which is an enlarged view of part A of FIG.
The premise of the optical information processing device in one embodiment of the present invention
FIG. 2 is a schematic diagram for explaining how to use a fiber plate .

In the figure, 11 is a fiber plate, 1
Reference numeral 2 denotes a one-dimensional array or two-dimensional array light emitting element, a one-dimensional array or two-dimensional array light receiving element, a one-dimensional array or two-dimensional array light switching element, a one-dimensional array or two-dimensional array It is a so-called parallel electro-optical function element such as an optical modulator, a spatial light modulator, or a flat optical element.

Also, in these figures , six parallel-type electro-optical functional elements, each having four parallel-type electro-optical functional elements disposed on both sides of one fiber plate, are shown.

First, the fiber plate 11 will be described. The fiber plate 11 is formed by integrating a large number of optical fibers, and can easily transmit two-dimensional parallel data such as an image.

As shown in FIG. 2, when two-dimensional parallel data is transmitted with the parallel-type electro-optical function element closely or almost in contact with the fiber plate 11, the degrees of freedom to be adjusted are up, down, left, and right. There are only three directions of rotation and rotation. That is, the degree of freedom to be adjusted is halved compared to the case where an image is transmitted by a lens system.

In other words, in such an arrangement, as long as the relative position between the parallel electro-optical function elements is determined, the parallel movement or rotation of the fiber plate 11 during that time can be used for information transmission between the parallel electro-optical function elements. Basically has no effect. In other words, you equivalent to a bulk type optical element of the prior art
Off Aibapureto 11, there is no need for precise position adjustments.

Generally, in an optical information processing apparatus in which many parallel-type electro-optical function elements are organically connected,
Since the degrees of freedom are closely related to each other, the complexity of adjustment of the entire apparatus is expressed not by the number of degrees of freedom itself but by the factorial of the degrees of freedom.

Thus, the effect of reducing the complexity of precision adjustment of the entire apparatus is extremely high only by halving the degree of freedom of adjustment for one parallel operation element for each parallel operation.

[0056] Further, the fiber plate 11 itself, which corresponds to a bulk-type optical element, since the position adjustment required, the
Position adjustment of the optical information processing system having such a configuration is extremely simple.

The fineness of the pixel in such a configuration is basically determined by the diameter of the fiber constituting the fiber plate 11. It is easy to manufacture a fiber plate 11 made of fibers having a diameter of about 25 μm, and a fiber plate having a diameter of about 10 μm can be manufactured.

[0058] Also in the optical information processing apparatus using a conventional lens system by, so has the diffraction limit in proportion to the wavelength, this is to use light in the infrared region from the visible region
The optical information processing apparatus having such a configuration is not inferior to the conventional optical information processing apparatus in the fineness of its pixels.

Next, the parallel type electro-optical element 12 is bonded to the fiber plate 11 with a transparent resin such as an ultraviolet curing resin. Parallel electro-optical function element 1
Adjustment of the relative position between the two is performed by applying an ultraviolet resin-cured resin to the adhesive surface between the parallel-type electro-optical function element 12 and the fiber plate 11 and bringing the parallel-type electro-optical function element 12 into close contact with each other. It can be performed by sliding on the surface, and the position adjustment is extremely simple.

At the stage where the position can be adjusted, the ultraviolet curable resin is cured by irradiating ultraviolet rays, and the parallel type electro-optical function element 12 and the fiber plate 11 are stably connected.

Since the parallel type electro-optical element 12 and the fiber plate 11 are directly bonded, they are stable against vibrations applied to the apparatus and environmental temperature fluctuations, and the relative positional relationship hardly fluctuates.

Further, unlike the configuration via the lens system according to the prior art, since there is no air between the components and they are arranged in close contact with each other, the influence of the flow of air and the turbulence thereof is eliminated. Furthermore, the volume of the entire device is also that Do can be greatly reduced.

In the following, more specifically, the fiber play
Configuration example in which parallel electro-optical function elements are connected using
It will be described.

More specifically , the two-dimensional parallel data has a function of branching into two parts , performing different processing on each part, and synthesizing again.

FIG. 3 shows the use of such a fiber plate.
FIG. 4 is an enlarged view of a portion B of the configuration example shown in FIG.

3 and 4, reference numeral 22 denotes a light-emitting element array, 23 denotes a plate-type branching element, 24 and 25 denote spatial light modulators, 26 denotes a plate-type combining element, and 27 denotes a light-receiving element array. These are parallel-type electro-optical function elements, and are connected via a fiber plate 21.

Reference numeral 28 denotes a fitting structure, and the flow of optical information of the optical information processing apparatus is indicated by a thick line 29.

The two-dimensional parallel data is stored in the light emitting element array 22.
Displayed above and generated as optical information. The generated optical information is transmitted to the flat branch element 23 via the fiber plate 21.

Next, the flat branching element 23 branches the optical information (two-dimensional parallel data) into two while maintaining the parallelism. The split optical information is transmitted to different spatial light modulators 24 and 25 via the fiber plate 21, respectively, and after being subjected to different processes, is transmitted to the flat-type combining element 26 via the fiber plate 21. .

In the flat plate type combining element 26, the two pieces of optical information are combined again, and the combined optical information is transmitted to the light receiving element array 27 via the fiber plate 21. The optical information transmitted to the light receiving element array is converted into an electric signal as processed two-dimensional parallel data and output.

[0071] Furthermore, parallel-type electro-optical functional element, eg, between the flat plate type combining element 26 and the fiber plate 21,
A fitting structure 28 is provided.

With this fitting structure 28, the position adjustment between the parallel electro-optical function elements is automatically performed. Further, even after the parallel-type electro-optical element and the fiber plate are bonded, the relative position does not fluctuate very much due to vibration or environmental temperature fluctuation.

[0073] This good sea urchin, by providing a fitting structure, not only the simple is good Ri further position adjustment, also increased mechanical stability, it a practical and industrial production which may be configured
You .

Incidentally, using such a fiber plate,
And the structure, the two-dimensional parallel data 2 branches, each space
Enters the optical modulator, performs different processing, and combines again
, And the ones that can be combined with many algorithms and architectures have been proposed as
There is also .

Hereinafter, characteristic basic components of the present invention and
More functional multiple types using possible fiber plates
Parallel-type electro-optical functional elements,
Configuration in which a controller and readout light supply are combined and connected
Will be described.

FIG. 5 is a sectional view of the specific basic components.

Reference numeral 51 denotes an optical writing type spatial light modulator;
Is a readout light supply device, 53 is a flat optical connection element, 54 is a fiber plate, 55 is a writing surface, 56 is a reading surface, 57 is input light, 58 is readout light, 59 is an external light source, and 550 is output light. .

Although these components are shown separately from each other, they are actually connected using a predetermined adhesive or the like, and this connection is the same in other examples.

On the writing surface 55 of the spatial light modulator 51,
The input light 57 carrying the two-dimensional parallel data represented by the two-dimensional image is irradiated, and the two-dimensional parallel data is written.

Since the effective reflectivity of the reading surface 56 of the spatial light modulator 51 changes depending on the written data, by supplying the reading light 58 to the reading surface 56 of the optical writing type spatial light modulator 51, The written two-dimensional parallel data can be read.

The read light is supplied by a read light supply 52,
The light reflected on the reading surface 56 of the optical writing type spatial light modulator 51 carries two-dimensional optical information, passes through the reading light supply device 52, and propagates to the flat plate type optical connection element 53.

The spatial light modulator 51 includes a flat optical connection element 5
In the case of No. 3, it plays the same role as the integrated light emitting device.

More specifically, the spatial light modulator 5
The role of 1 is processing of irradiated optical information by threshold processing, latch operation, and the like. Furthermore, using a spatial light modulator in which a logic circuit or the like is integrated and added, a more advanced process regarding the light intensity of each pixel is executed, and then the effective reflectance of the reading surface can be set.

If pulsed light is used instead of continuous light for the readout light, a clock function can be provided.
In the optical information processing apparatus comprising a large number laminated basic component, such as a configuration makes it possible to perform more complex and advanced processing.

The reading light supplier 52 is an element for supplying a reading light 58 having a uniform light intensity to the reading surface 56 of the spatial light modulator 51 as its name implies. Light having a stable wavelength and light intensity is supplied from the external light source 59 to the reading light supplier 52.

Therefore, in such a configuration , the combination of the optical writing type spatial light modulator 51 and the reading light supplier 52 produces heat and heat storage in a conventional configuration using a high density integrated light emitting element. Difficulties can be overcome.

That is, in such basic components, necessary light is supplied from an external light source 59 installed outside the basic components, and does not have a spontaneous light emitting portion. That is, generation and accumulation of heat in the optical information processing apparatus according to the present invention having a laminated structure can be suppressed to a minimum, and there is no practical problem.

In addition, since it is easy to use a light source having high light output intensity and high wavelength stability, there is no need to consider uniformity between individual devices, which is a problem when using an integrated light emitting device. .

As described above, the optical writing type spatial light modulator 5
1 and the read light supply unit 52 and Ri by <br/> to combining, while overcoming various difficulties arising in systems using integrated light-emitting element, in which it is possible to realize the same function.

In general, for optical information processing, functions such as branching, synthesizing, shifting, and internal arrangement conversion of two-dimensional parallel data are functions related to the essence thereof.

The optical information processing technique is particularly superior to the conventional information processing technique in that it can process two-dimensional parallel information while maintaining parallelism. In the case of the conventional temporal serial information processing, a switching operation is the basis of the information processing function.

In such basic components as well, the optical writing type spatial light modulator 51 exists as a portion corresponding to the switching function.

However, in the two-dimensional parallel type information processing technology, the switching function is subordinate, and the central one is control of the flow of optical information and conversion of internal arrangement.

That is, in such basic components, the flat optical connection element 53 is provided with the optical writing type spatial light modulator 51.
, Branching, synthesizing, shifting, internal arrangement conversion, and the like of the two-dimensional parallel data read from.

For example, when combining two two-dimensional parallel data, since light has a property of mutual incoherence, two
It is easy to intersect and combine two lights carrying dimensional parallel data.

However, it is not possible to obtain one light which carries the synthesized two-dimensional parallel data.

In this configuration , the two lights to be synthesized are combined with the optical writing type spatial light modulator 5 as a basic component.
1 to the writing surface 55 and read light supply element 52
The reading light 58 by the optical writing type spatial light modulator 51
By irradiating the reading surface 56 with the reading light supply device 52 which is a component of the next stage, the combined information can be transmitted to the flat-plate type optical connection element 53.

The next-stage read-out light supply unit 52 and the flat-plate-type optical connection element 53 read out the two-dimensional parallel data synthesized from the optical write-in type spatial light modulator 51 as one piece of optical information, and further perform a new process. And outputs it as output light 550.

Such a flat optical connection element 53 and the like can be constituted by, for example, an element utilizing the planar optics technology introduced in the conventional technology, but is simply developed in a planar manner as in the conventional configuration. If this is done, the device will consume a large area.

[0100] However, taking a configuration as this, even when using planar optical technology, two-dimensional parallel data branch,
Functions such as composition, shift, and internal layout conversion can be relatively easily realized, and even when a large-scale and complicated configuration is realized, the system does not simply spread two-dimensionally. .

That is, the spatial light modulator and the readout light supplier
And basic components with a planar optical connection element, while taking advantage of the planar optical technique, a configuration capable of effectively ensuring scalability.

In summary, in such basic components, the spatial light modulator 51 and the readout light supplier 5
2. The basic structure of the optical information processing apparatus configured under the uniform guidelines because it includes all the essential and basic functions related to the optical information processing technology of the flat optical connection element 53 and has a simple configuration. It is an extremely excellent core composition.

[0103] Further, to achieve higher order optical information processing function, the basic components such as this, via a fiber plate, indicates that may be further sequentially stacked.

[0104] Further, this basic component, consists of optical writing type spatial light modulator 51, the readout light supply 52 and planar optical connection element 53, as described above, appropriate to these configurations It is also possible to variously select and combine them, and it is also possible to cause the basic components configured as described above to perform the unit function for the optical information processing device.

That is, by combining these unit functions corresponding to the higher-order optical information functions to be realized,
That is, a large-scale and complicated optical information processing apparatus can be constructed by stacking predetermined basic components.

As described above, in this embodiment , a large-scale optical information processing system can be constructed only by a simple and unified guideline of a combination of basic components having basic unit functions. And it is easy to construct a CAD system for designing a complex system.

Further, since it has a unified configuration, industrially practical optical information processing apparatuses can be produced dramatically easily.

[0108] (Example 2) Hereinafter, a second embodiment of the present invention will be described with reference to the drawings.

FIG. 6 is a block diagram showing a structure usable for an optical information processing apparatus.
FIG. 4 is a cross-sectional view of an embodiment of an extended basic component.

In FIG. 6, reference numeral 71 denotes an optical writing type spatial light modulator; 72, a reading light supply unit; 77 and 78 are input lights carrying two-dimensional parallel data, respectively, 711, 712, 713, 714, 715, 7
16 and 717 are holographic elements, 72
Reference numerals 1 and 722 denote output lights.

The unit functions of the basic constituent elements shown in this embodiment are that the two-dimensional parallel data carried by the input light 78 is divided into two, and the position inversion data of the two-dimensional parallel data carried by the input light 77 is It is to overlap.

Of course, the unit functions of the basic components according to the present embodiment are not limited to those described above. For example, basic components having unit functions such as four-branch, synthesis, shift synthesis, and perfect shuffle are also applicable. If necessary, it can be realized by an equivalent configuration.

In this embodiment, the optical writing type spatial light modulator 71 is, for example, a spatial light modulator using a ferroelectric liquid crystal. This has a structure in which a ferroelectric liquid crystal and amorphous silicon are stacked to apply a voltage. The amorphous silicon side is the writing surface, and the ferroelectric liquid crystal side is the reading surface.

On the writing surface side (left side as viewed), the input light 7
When irradiated with 7, 78, the amorphous silicon in the portion irradiated with light shows photoconductivity, and the voltage applied to the amorphous silicon and the ferroelectric liquid crystal is applied only to the ferroelectric liquid crystal. The orientation of the liquid crystal changes.

If a polarizing plate in an appropriate direction is provided on the reading surface side (right side as viewed), the effective refractive index on the reading surface side changes accordingly.

The reading light 79 is supplied from an external light source (not shown), and is supplied to the reading surface of the spatial light modulator 71 via the reading light supplier 72.

In this embodiment, an element to which the planar optical technique is applied is used as the readout light supplier 72.

The light 79 supplied from the external light source is first expanded by the holographic element 711. Next, at the same time as the parallel light is converted by the holographic element 712, the traveling direction is changed, and the light is uniformly irradiated on the readout surface of the spatial light modulator 71 via the holographic element 713.

The read-out light supplier 72 is not limited to an element to which the planar optical technique is applied, but may have several configurations such as an element utilizing an image propagation mode and a scattering mode of a fiber plate.

The light carrying two-dimensional parallel data reflected by the readout surface of the spatial light modulator 71 passes through the readout light supply 72 and enters the flat optical connection element 73.

The flat optical connection element 73 is an element utilizing a planar optical technique in this embodiment. Here, the input light 78
Is split into two via a holographic element 714, and one of the split lights is output as it is as output light 722 via a holographic element 716.

On the other hand, the arrangement of the light corresponding to the input light 77 is reversed via the holographic element 715. The light corresponding to the input light 77 and the other one of the lights corresponding to the input light 78 are combined and output as output light 721 to the next stage.

The flat optical connection element 73 is not limited to an element to which planar optics is applied, but may be a branch element to which a fiber plate is applied, for example.

As described above, an optical information processing apparatus having a unit function of branching, combining, and arrangement conversion is realized by the basic components that are further expanded in this embodiment, and furthermore, the same as this embodiment. With such a configuration, other unit functions necessary for optical information processing can be easily realized.

[0125] (Embodiment 3) In this example, an example of an optical information processing apparatus capable of realizing two-dimensional parallel data XOR (exclusive OR) by combining the basic components, a third embodiment This will be described with reference to the drawings.

FIG. 7 is a sectional view showing the structure of this embodiment. FIG. 8 shows that each of the basic components includes
2D parallel data is processed and converted.
This is a case where × 2 two-dimensional parallel data is given as input data.

Reference numeral 81 denotes a first basic component, 82 denotes a second basic component, 83 denotes a third basic component, 84 denotes a fourth basic component, 85 denotes a fifth basic component, and 86 denotes a fifth basic component. It is a fiber plate, 1-5 in FIG. 7 and FIG.
Each corresponds to the first to fifth basic components.

XOR of two-dimensional parallel data can be realized only by laminating first to fifth basic components having different unit functions via a fiber plate 86.

The first basic component 81 shown in FIG.
It has a unit function to split the input two-dimensional parallel data into two. The second basic constituent element 82 has a unit function of performing four-dimensional parallel data by expanding and deforming the two-dimensional parallel data. The third basic component 83 has a unit function of synthesizing two-dimensional parallel data.

Next, the manner of processing conversion of two-dimensional parallel data will be described in detail with reference to FIG. 8, using 91 and 92 as examples of input parallel data.

In the two-dimensional parallel data shown in FIG. 8, a white portion indicates a portion having a high light intensity, a black portion indicates a portion having a low light intensity, and a shaded portion indicates a gray portion having a light intensity in between. Indicates that

In the first basic component, the two input two-dimensional parallel data are each branched into two. In the second basic component, the two-dimensional parallel data is enlarged and deformed to create four types of two-dimensional parallel data.

And, in the third basic component,
Four types of two-dimensional parallel data output from the second basic component are combined to create two identical two-dimensional parallel data.

The two-dimensional data synthesized in the third basic component shown in FIG. 8 is composed of white, gray (shown by oblique lines), and black parts.

In the fourth basic component, the two-dimensional parallel data output from the third basic component is subjected to threshold processing with white and gray as boundaries, and then subjected to shift synthesis. The type of logical operation is determined by the manner of shifting at this time.

In the fifth basic constituent element, the two-dimensional parallel data subjected to the shift synthesis is first subjected to threshold processing this time on the boundary between black and gray. Further, in order to extract a meaningful part of the two-dimensional parallel data, a spatial filtering process is performed, and then the arrangement is reduced and deformed.

Among the unit functions described above, the threshold processing and the spatial filter processing mainly belong to the spatial light modulator included in the basic components. On the other hand, the unit functions of branching, combining, and deformation mainly belong to the flat-plate type optical connection element.

Therefore, also in the present embodiment, complicated optical information processing can be performed by combining the basic components including the configuration such as the spatial light modulator and the flat optical connection element.

Further, the configuration of the present embodiment can be easily extended to an optical information processing apparatus in which 16 types of logical operations can be arbitrarily selected by slightly expanding the functions of the third and fourth basic components. It is possible.

There are 16 types of selection combinations, which correspond to 16 types of logical operations.

It is easy to provide the spatial light modulator with a plurality of areas in which writing can be individually controlled. For example, in the case of a spatial light modulator using a ferroelectric liquid crystal, this can be achieved by dividing the electrodes to which the drive voltage is applied and controlling the respective applied voltages.

As described above, in the configuration according to the present embodiment,
Not only a single-function logical operation optical information processing apparatus but also a multi-function logical operation optical information processing system can be easily realized.

In summary, by stacking five basic components each having a different unit function,

FIG. 1 is a schematic cross-sectional view of a configuration of a large-scale optical information processing apparatus in which optical information processing apparatuses having different functions are connected in parallel and further developed into a large-scale system. The optical information processing device connected at this time can be used as long as it is not only the device described in other embodiments but also other equivalent devices.

FIG. 9 shows a configuration in which a plurality of optical information processing apparatuses 61 according to the present embodiment are connected in parallel by being sandwiched between two planar optical elements 62 and 63. Numerals 64 and 65 represent the states of light propagating in the planar optical elements 62 and 63 for optical information.

When constructing a large-scale optical information processing apparatus,
It is not enough to simply laminate the basic components described in the above embodiments of the present invention via a fiber plate, and it is not enough to optically connect optical information processing apparatuses having a certain set of functions in parallel. It is necessary to build a large-scale system.

For parallel optical connection of such an optical information processing apparatus, a configuration using a planar optical element is most suitable.

In this embodiment, the planar optical elements 62 and 63 are made of a glass plate. The light carrying the light information obliquely emitted from the optical information processing device 61 passes through the inside of the planar optical elements 62 and 63 through a phenomenon called total reflection or a micro-optical element such as a reflecting mirror or a holographic element. As shown in 64 and 65, the light arrives at another optical information processing device while progressing in a zigzag manner.
Thus, the respective optical information processing apparatuses can mutually exchange information.

In this embodiment, it is possible to realize a practical optical information processing apparatus which is easy to design based on the unified guideline and which is easy to industrially produce.

The configuration according to the present embodiment is a technology for expanding into a large system based on an optical information processing module, so to speak, and is very versatile.

It can be realized.

[0159] Example 5 In the present embodiment, from the moving image data, the moving object extraction function of extracting only those moving, an example of an optical information processing apparatus realized by combining the basic components, the Embodiment 5 will be described with reference to FIGS. 10 and 11. FIG.

FIG. 10 is a diagram showing the configuration of the optical information processing apparatus according to the present embodiment. FIG. 11 shows the state of processing of two-dimensional parallel data in each basic component in order with time. FIG.

Reference numeral 101 denotes a first basic component, 102 denotes a second basic component, 103 denotes a third basic component,
4 is a fourth basic component, and 105 and 106 are fiber plates.

In this embodiment, an optical information processing apparatus having a moving object extracting function can be realized by stacking four basic components as shown in FIG.

More specifically, the first basic component 101 has a function of dividing moving image data into two. The second basic component 102 has a black-and-white inversion function. Another fiber plate 106 is stacked in parallel with the second basic component 102 between the fiber plates 105 sandwiching the second basic component.

One of the moving image data branched into two by the first basic component 101 is the second basic component 1
02, and the other passes through the fiber plate 106 and enters the third basic component 103.

In the third basic component 103, the moving image data that has been inverted in black and white in the second basic component 102 and the moving image data that has passed through the fiber plate 106 are combined. The synthesized moving image data is subjected to threshold processing by the fourth basic component 104, and moving object extraction data is output.

The manner in which moving object extraction data is output in the configuration of this embodiment will be described with reference to FIG.

[0167] 1 to 4 in FIG. 11A correspond to 1 to 4 in FIG.
4 corresponds to the first to fourth basic components.

A clock is supplied to the spatial light modulator in each of the basic components, and the moving image data is temporally sampled. At the same time, the sampled moving image data is sequentially transferred to the next basic element. The clock operation of such a spatial light modulator is
It can be easily realized by supplying an electric drive pulse or a pulsed readout light.

FIG. 11A shows that, at time t = A, the moving image input data input to the first basic component is used as sampling data A by the clock supplied at time t = A. The state latched by one basic component is shown.

The next clock is supplied at time t = B shown in FIG. The first basic component latches the sampling data B and transfers the data A to the second basic component and the third basic component. The second basic component latches the data A by inverting black and white, and the third component latches the data A as it is.

Next, the time t = C shown in FIG.
Then, when the next clock is supplied, data B and black-and-white inverted data A are transferred to the third component, and both are optically combined. In this fourth basic component,
The combined data is subjected to threshold processing.

FIG. 11D shows data A, black-and-white inverted data A of data A, data B, data A, and data A when moving image input data of a moving circular object and a stationary circular object is input. 7 specifically shows the composite data of B.

As can be easily understood from FIG. 11D, in the composite data of the data A and the data B, the image of the stationary circular object is deleted, and only the image of the moved circular object remains.

In the structure of this embodiment, since the individual pixels constituting the moving image data are simultaneously subjected to the parallel distributed processing, the processing speed is extremely high, and the real-time high-speed moving object processing detection can be executed very easily. .

In summary, in the optical information processing apparatus according to the present embodiment, the real-time high-speed moving object extraction function can be easily realized by the configuration according to the present invention, which is mechanically stable and easily optically adjusted. .

[0176] (Embodiment 6) In this embodiment, the outline extraction function of extracting from the image data outline only, an example of an optical information processing apparatus realized by combining the basic components, as a sixth embodiment This will be described with reference to the drawings.

Reference numeral 121 denotes a first basic component, 122 denotes a second basic component, and 123 denotes a third basic component.

The first basic component 121 has a function of dividing input data into two equal data. The second basic constituent element 122 generates composite data in which one of two equal two-divided data is inverted in black and white and then shifted vertically and horizontally and superimposed.
FIG. 12 (b) shows four combined data when circular image data is input.

In the third basic component 123, the four shift composite data created by the second basic component 122 are subjected to threshold processing and then composited. At this time, threshold processing is performed by setting a threshold value for extracting only the unfilled or hatched portion shown in FIG. 12B, that is, only the brightest portion, of the shifted combined data. Then, by synthesizing the shift composite data subjected to the threshold processing, it is possible to easily obtain contour extraction data as shown in FIG.

Also in this embodiment, contour extraction is performed by performing parallel distributed processing on each pixel of the input parallel data. Therefore, the configuration according to the present invention, which is mechanically stable and easy to optically adjust, can easily realize ultra-high-speed real-time contour extraction.

(Embodiment 7 ) To construct an optical information processing apparatus having advanced functions, it is necessary to provide a parallel data feedback function in the system.

For example, the feedback function can be realized by using the above basic components .

In this embodiment, an example of an optical information processing apparatus having a feedback function is shown as a seventh embodiment in FIG.
3 and FIG.

FIG. 13 is a cross-sectional view of the basic components necessary for realizing the feedback function.

The basic element for feedback A128 shown in FIG. 13A is a basic element having a function of synthesizing the fed back data with other parallel data. Reference numeral 131 denotes a spatial light modulator; 132, a readout light supplier; 133, a flat optical connection element; and 138, a fiber plate.

The basic component B129 for feedback shown in FIG. 13 (b) is a basic component having a function of branching feedback parallel data from parallel data. Reference numeral 134 denotes a spatial light modulator; 135, a readout light supply unit; 136, a flat optical connection element; and 139, 140, a fiber plate.

The basic components described in the previous embodiment are:
It is laminated via a fiber plate to realize a complex and advanced information processing function as a whole. The basic components for feedback of the present embodiment are no exception, and their functions are exhibited by being laminated together with other basic components via the fiber plates 138 and 140.

First, the configuration and function of the basic component B for feedback will be described.

As shown by an arrow from the left side of the feedback basic component B129, the input light carrying parallel data from the preceding basic component is shown. The subsequent flow of light in the basic component B for feedback is also indicated by arrows in the figure.

First, the input light carrying the parallel data is written to the spatial light modulator 134 constituting the basic component B129 for feedback, and the parallel data is read by the read light supplied by the read light supplier 135.

In the flat optical connection element 136, the light carrying the parallel data is split, and at least one of the split lights is returned to the input light direction to become feedback light.

As shown in the figure, a fiber plate 139 is provided in place of the spatial light modulator and the readout light supply unit so that the feedback light passes therethrough. Feedback is provided in the component direction.

Next, the basic feedback element A128 shown in FIG. 13A will be described. In the feedback basic component A128, FIG.
Similarly to the basic components described in 3 (b), the input of light carrying ordinary parallel data is performed from the direction of the arrow shown on the left side of the feedback basic component A128.

On the other hand, the light fed back enters the flat optical connection element 133 from the direction of the arrow shown on the right side of the basic component A for feedback.

The flat optical connection element 133 has a function of changing the traveling direction of the feedback light to match the direction of the flow of the normal optical information.

That is, among the basic components A, B128 and 129 for feedback, the flat optical connection elements 133 and 136 play an important role in realizing the feedback function. The feedback function is realized by changing the traveling direction of light at this portion by 180 °.

In this case, the configuration of the flat optical connection element may be one in which a flat micro optical element or the like is arranged on the surface thereof by applying the so-called planar optics technology, and changes the traveling direction of light. This is realized very simply.

FIG. 14 is a block diagram of an embodiment in which the basic components A and B for feedback described in FIG. 13 are incorporated in an optical information processing apparatus to form a feedback loop.

Reference numeral 141 denotes a basic element A for feedback, 142 denotes a second basic element, 143 denotes a third basic element, and 144 denotes a basic element B for feedback.
These are mutually laminated via the fiber plate 146.

The direction of the normal parallel data flow is from the feedback basic component A 141 to the feedback basic component B 144 as indicated by the arrow from right to left in the figure.

When the parallel data that has proceeded in the normal direction reaches the feedback basic component B144 via the second basic component 142 and the third basic component 143, it is split into at least two components. At least one of the branched parallel data changes its direction and is incident on the fiber plate 145, and the feedback parallel data 14
It becomes 6.

The fiber plate 145 is laminated in parallel with the second basic component 142 and the third basic component 143, and the feedback parallel data 14
6 travels in a direction opposite to the direction of the normal parallel data flow and enters the feedback basic component A141. The direction of the feedback data 146 is changed by the feedback basic component A 141, and is returned to the normal parallel data flow direction.

[0204] Thus, in this embodiment, it can also be easily configured the feedback loop, it is possible to easily deal with a sophisticated and complex architectures and algorithms.
Moreover, there is no possibility that also ease and mechanical stability of the optical histological adjustment is lost.

(Embodiment 8 ) A vector-matrix product-sum operation using a so-called anamorphic optical system using a cylindrical lens is one of the typical examples showing the superiority of the optical information processing technology. The multiply-accumulate operation by this system is completely parallel processing,
Ultra-high-speed operation is possible even for a vector matrix having many components. Providing such a vector-matrix operation processing function is one of the essential requirements for a high-performance, high-performance optical information processing apparatus.

[0206] In this embodiment, by using the basic components, the vector - the product-sum operation between the matrix, (a _i) ×
The fact that (M _ij ) = (b _i ) is possible will be described with reference to FIG. 15 (i, j = 1, 2, 3,...).

FIG. 15 shows the present embodiment used for an optical information processing apparatus .
It is a block diagram of the vector-matrix product-sum operation part of an example, FIG.15 (a) is a top view, FIG.15 (b) is a side view.

[0208] This operation unit is composed of the first basic component 15
1, second basic component 152, third basic component 1
53 are laminated via a fiber plate 157.

[0209] The function of each basic component will be described below. Vector data (a _i ) 154 having n components and matrix data (M _ij ) 155 having n × n components are input to the first basic component 151.

The matrix data 155 is transferred to the second basic component 157 as it is. The vector data 154 is expanded and converted in the horizontal direction, and then transferred to the second basic component 157. That is, after this conversion, the data becomes matrix data and becomes the following n × n determinant.

[0211]

(Equation 1)

FIG. 16 shows an example of the configuration of the optical connection element 160 in the first basic component 151 that performs such conversion.

This optical connection element 160 is a slab waveguide 1
61 are laminated. Light incident on each of the laminated waveguides is easily diffused in the plane direction of the slab waveguide 161 but does not expand in the thickness direction. By utilizing this characteristic of the slab waveguide 161, the light carrying each component a _i of the vector data incident on the incident end 162 of each stacked slab waveguide 161 expands in the horizontal direction. By providing a microlens array or a mask at the emission end 163 of the slab waveguide, it is possible to extract n light beams carrying information _ai .

Next, the second basic component 152 has a function of synthesizing two matrix data sent from the first basic component. The synthesized matrix data has a size of 2n × n and is represented by the following determinant.

[0215]

(Equation 2)

Next, the third basic component 153 has an optical writing type spatial light modulator. The optical writing type spatial light modulator whose sensitivity can be changed by input optical information is used. The variable sensitivity optical writing type spatial light spatial modulator will be described in detail using the above-described combined matrix data as an example.

The variable sensitivity optical writing type spatial light modulator needs to have at least an n × n divided sensitivity variable area or pixel.

In each sensitivity variable area, the i-th row (2j−1) column and the i-th row 2j
The columns are entered as a set of data. The data to be written into each sensitivity variable area is the data in the i-th row (2j-1) column and is written with the sensitivity determined by the data in the i-th row and 2j column.

If the data thus written is read out by supplying readout light to the readout surface, matrix data represented by the following determinant can be read.

[0220]

(Equation 3)

The flat optical connection element 150 provided at the subsequent stage in the third basic component 153 has a structure in which slab waveguides 171 are stacked as shown in FIG.
This uses a slab waveguide in which the flat optical connection element 160 included in the first basic component is stacked, in reverse.

The n × n matrix data read from the spatial light modulator provided in the third basic component 153 at the stage preceding the flat optical connection element 150 is input to the input end 17.
2 is incident on the laminated slab waveguide 171.

The side face of the slab waveguide 171 has a reflective film 17
4 are formed, and the light that has entered the individual slab waveguides 171 is collected at the output end 173. That is,
The sum calculation of the light intensity is performed.

In this way, the output end 174 outputs vector data having n components as represented by the following equation.

[0225]

(Equation 4)

From this equation, it can be seen that this vector data is the product-sum operation result (b _i ) of the matrix (M _ij ) and the vector (a _i ).

[0227] The above-described basic components of the reference lever, conventionally, by using a cylindrical lens or the like, it takes a precise optical position adjustment vector - matrix operation optical system, an optical excellent mechanical stability It became possible to replace it with an optical system that can easily adjust the target position.
