DEVICE FOR OPTICAL ASSOCIATIVE SEARCH OF INFORMATION IN MEMORY UNIT Russian patent published in 1995 - IPC

FIELD: computer engineering. SUBSTANCE: device has group of multichannel emitting units 1 which serve for input of information in device represented by different wavelength of light beams. In addition device has unit 2 which serves for convergence of beams having different wavelength to joint multicolored beam. In addition device has multiplication unit 3, multipliers 5 serving for duplication of color image of pages with request conditions, controlled transparency units 7 which serve for displaying pages with associative conditions of different users. In addition device has light beam distribution units 8 which serve for distribution of light beams corresponding to different associative conditions and for selection between beams carrying conditions and reference beams. In addition device has projection units 4, light beam generation units 6 and focusing units 12 for beam generation, image separation unit 10 which serve for separation of color image into basic colors, photodetector units 11 which convert optical signals to electric ones, and control unit 12. EFFECT: increased functional capabilities due to execution of associative information search by several request conditions in multiprogramming mode for different types of memory units. 4 cl, 3 dwg
