DEVICE FOR PROCESSING OF TWO-DIMENSIONAL OBJECT IMAGES Russian patent published in 1997 - IPC

FIELD: image recognition. SUBSTANCE: device has serial circuit of light source 2, object sample 1, Fourier transform optical processor 3 and receiver 4. Said serial circuit is located along device optical axis 5. Light source has emitter 9 which outputs non-coherent beam of given area and shape. Output of emitter 9 is located on optical axis 5 and for elements 1 and 3 is located in position that represents object plane for projecting three- dimensional frequencies of device 3 into plane 7. Receiver 4 is designed as single receiver 8 which is located on optical axis 5 in plane for projecting three-dimensional frequencies of device 3 into plane 7. EFFECT: simplified design, decreased cost of information processing. 9 cl, 3 dwg
