OPTICAL COMPUTATIONAL UNIT Russian patent published in 1994 - IPC

FIELD: specialized computer technology. SUBSTANCE: output of radiation source is connected to input of the first optical splitter. Outputs of branches of the splitter are connected with inputs of transparencies of the first group through corresponding transparencies of the second group. Outputs of the first group transparencies are connected with inputs of integrated branches of the second optical splitter. Output of the second optical splitter is connected to input of the first optical amplifier. Outputs of any N optical amplifiers connected in series are connected to inputs of corresponding splitters of the group. The first branch of the latter unit is connected to the input of corresponding transparency of the first group. The second branch is connected to input of the same optical amplifier. The third branch is connected to input of the next optical amplifier. Output of the third branch of the last splitter has to be output of the device. EFFECT: simplified design; widened functional capabilities of the device. 1 dwg
