FIELD: electro-optics. ^ SUBSTANCE: device for forming and processing images has focon assemblage onto wide edges of which the image is projected. Narrow edges of assemblage are connected with cells of CCD array through optical splitters 1:5 array, spatial filters X and Y. Each filter has array of electrically controlled optical couplers made on the base of three joined waveguides. Device also has control unit. Bipolar control voltage generated by control unit is applied to electric inputs of any coupler. Binary code of coupler and binary code of coefficients defined by amplitude-frequency characteristic shape enters inputs of control unit. Control unit has decoder and control voltage forming and memorizing units. Each unit has two digital-to-analog converters and one register. Number of units for forming and memorizing control voltages corresponds to number of couplers. Device performs spatial filtering due to weighted summation of optical signal from image elements disposed next to each other by means of splitters and electrically controlled fiber-optical couplers. ^ EFFECT: widened functional capabilities due to introduction of preliminary image processing. ^ 4 dwg |
