Optical switch 1 is designed to provide fully space-time communications between operands. Switch 1 may consist, for example, of a diffraction grating optically coupled to a hologram matrix, at the output of which are located collective and collimating objectives that are mutually in each other's focal planes. The diffraction grating can be performed on gelatinous layers or bleached photo layers. A hologram matrix can be performed on bleached photo panels or

gelatinous layers, or it can be made on any suitable reversible medium, providing an efficient matrix formation. As a hologram matrix, a multi-element synthesized hologram can also be used.

Correction unit 2 is designed to ensure parallel light beams and their power amplification. Block 2 may consist, for example, of an optically controlled transparency, the entrance of which is the entrance of the block, a beam-splitting cube is located at the exit of the transparency, the first output of which is optically coupled to the laser through a telescope, and the second output of the cube is output of block 2. Optical controlled trans-ant can be made on the basis of liquid crystals.

The optical switch 3 serves to project an image of each element of the first page of the operands, which enters the input of the converter onto a certain element or group of elements of the corresponding column of the second page of the operands displayed in the operation unit 4. The block 3 may consist, for example, of a successive diffraction grating, matrix holograms located in the main plane of the collective cylindrical lens and the collimating cylindrical lens, which is located injective mutually at focal planes of each other. The diffraction grating and the hologram matrix can be

Operational / unit 4 is designed to compute all sixteen basic logical boolean functions.

The beam dilution unit 5 is designed to separate the light beams in space, pass them through different rows of cells of block 4, which ensures that in each cell of block 4 logical operations on several operands of the first page, separation of the results of operations in the converter and their direction to its correspondingly different exits. Block 5 may be made in the form of an integral or composable matrix of wedges. Each row of the wedge matrix is a linear raster consisting of wedges having the same refractive angles. The refracting angles of the optical wedges of the linear rasters stepwise change from the outermost rows towards the center of the matrix, on either side of which the linear rasters of the optical wedges are the same and are turned relative to each other on

180. The integral matrix of wedges N0-35 (B) is also in the direct paraphase code, with

It can be made, for example, by stamping resin, plastic or gelatin, glass etching or spraying methods.

The focusing unit 6 may consist, for example, of two lenses arranged mutually in the focal planes of each other and the lenticular raster, the front focal plane of which coincides with the principal plane of the second objective.

The beam dilution unit 7 is designed to direct light beams that display the results of calculations to different outputs of the output, for example, a memory device, through the input channel of the control unit 9, the buffer drive and the fourth driver control unit to the operation unit 4. In this case , suppose that there is no direct correspondence between the processed operands of pages A and B.

At the command of the sync pulse generator of the control unit 9, the control signal drivers supply voltages to the blocks and in the optical switches 1 and 3, matrices Q of holograms are formed that provide the necessary communication topologies between cells displaying the corresponding operands of the first (A) and second (B) pages.

The beam forming unit 8 can be performed, for example, in the form of a telescope.

The control unit 9 (Fig. 2) provides the operation of the converter and may consist, for example, of a sync generator 10, of form and frequency. lep 11–14 control signals from nepf-th to fourth, buffer storage 15 and input channel 16, with the outputs of the first to the third clock generator being connected to the first, second and third control signal generator, the outputs of which are connected to the control inputs respectively optically1 o I

the switch 1, the correction unit 2 and the optical switch 3. The fourth and fifth outputs of the clock generator are connected to the first inputs of the input channel and the buffer storage, the output of which is connected to the controlled input of the operation unit through the fourth driver of control signals. The second input of the buffer accumulator is connected to the output of the input channel, the second input of which is the input of the control unit.

The Converter operates as follows.

Suppose that optical signals are displayed at the input of the transducer that display the first page of operands (A), for example, in the forward paraphase code, while the cells forming the paraphase mark are located in one line. Electrical signals displaying the second page of the operand

the output, for example, of the memory device, is fed through the input channel of the control unit 9, the buffer storage device and the fourth driver of the control signals to the operation unit 4. In this case, suppose that there is no direct correspondence between the processed operands of pages A and B.

At the command of the sync pulse generator of the control unit 9, the control signal drivers supply voltages to the blocks, and in the optical switches 1 and 3, hologram matrices are formed that provide the necessary communication topologies between cells displaying the respective operands of the first (A) and second (B) pages.

At the same time, in the optical switch 1, a hologram matrix is established (or it is formed operatively on a reverse carrier when fed to it directly) 1 and from block 9), which forms strong links between

input and BbixoAoNr switch 1, which provide at the output of switch 1 grouping into each j-th (where, 2,3, ..., n, and n is the maximum number of columns in the operands page) column of all arbitrarily located in page A px (where p 1,2,3, ... ,, a is the maximum number of operands in the column of page A) of the operands that must be processed in the cells of the corresponding j-ro column of the elements of the operation unit 4, and these p- E operands of page A can simultaneously be processed in other (different) columns of block 4, which is ensured by splitting In this way, from randomly arranged operands of page A at the input of the converter, switch 1 forms at its output a specific location (page A), in which the operands to be processed in one column of cells of block 4 are located in the corresponding one column of page A.

Optical signals, which carry the operands of page A, through the correction unit 2 arrive at the input of the optical switch 3 so that they are parallel to the optical axis of the switch and are amplified in power. In switch 3, the light beam corresponding to each pth operand passes through the diffraction grating and multiplies and directs the entire hologram matrix to all K-e (where K 1,2,3, ..., ha, am is the number of operands in column) of the j-ro column of the elements of block 4 in which this pth operand should be processed. In this case, different p-th operands can pass through a different number of K-x cells in the j-M column of cells of block 4.

The light beams representing the p-th operands of the j-ro column of page A, using cylindrical lenses, illuminate each corresponding K-th cell of the j-ro column of block 4 at appropriate certain angles. The latter can calculate any of the sixteen basic logical booleans

functions.

Light beams passing through the same row of cells of block 4 pass through the corresponding one line of wedges of beam spreading block 5 and acquire a certain angular displacement in the orthogonal plane (Fig. 16).

The focusing unit 6 transfers the light distribution obtained after block 5 in the form of micro-frames to block 7 of the beam propagation. Block 7, through block 8, directs the light beams representing each column of the image existing on the code of block 6 to the corresponding output of the converter. The total number of converter outputs is m.

Thus, if the number of operands in a page is equal to TCP, then the converter can simultaneously calculate (mxnjm logical operations and represent them on m different outputs, i.e., the performance of the proposed converter is m times higher than the known one. For example, RCLI page contains Yu xY operands, then the performance of the converter increases 10 times.
