OPTICAL DIGITAL MULTIFUNCTIONAL CORRELATOR Russian patent published in 1997 - IPC

FIELD: computer engineering, devices for optical signal processing. SUBSTANCE: device has multiple-channel spectral illuminating unit 1, optical multiplexers group 2, optical branches group 3, optical modulators group 4, optical gates group 5, optical joints group 6, spectral separators group 7, simple-search photodetectors unit 8, complex-search optical joints group 9, spectral separators group 10, complex-search photodetectors units 11-1, ..., 11-s, and control unit 12, which has inputs 13-1, ..., 13-(s+4) and outputs 14-1, ..., 14- (s+4). EFFECT: increased efficiency, increased functional capabilities due to detection of total number and positions of equal bits when complex associative information search is run in parallel for multiple requests by means of optical logical hardware. 2 dwg
