FIELD: computer engineering. SUBSTANCE: device is designed for solving a task of complex associative search of information by several conditions by means of optical methods in different memory units. device has multichannel emitting unit 1 which serves for input of information in device represented by light beams, beam distribution unit 2 and sixteen light beams for arranging light beams. In addition device has controlled transparency unit 4 for displaying page with conditions of request, beam distribution unit 7 which serves for three-dimensional distribution of beams carrying conditions and reference beams. In addition device has optically controlled transparency 15 for short- term information storage, optical transducers 18 providing wrong phase reading, projection unit 6 and beam generating units 10. In addition device has control unit and photodetectors for conversion of optical signals to electric ones and monitoring coincidences. EFFECT: increased speed and decreased cost of memory units. 2 dwg
