ASSOCIATIVE OPTICAL CORRELATOR FOR MEMORY UNIT Russian patent published in 1995 - IPC

FIELD: computer engineering. SUBSTANCE: device has multichannel emitting unit 1 which serves for input of information represented by light beams into correlator. In addition device has projection unit 2 which serves for projection of image of each associative condition onto all conditions of request. In addition device has controlled transparency unit 3 which serves for displaying page with conditions of request, beam distribution unit 4 which is made as matrix of prisms for dividing light beams that correspond to different associative conditions. In addition device has focusing unit 5 which adds optical signals, photodetector 6 which converts optical signals to electric ones, and control unit 7. EFFECT: increased efficiency of correlator when associative search for several conditions in request is performed. 4 dwg
