Paper Abstract

An optical heterodyne correlator, in which the functions of overlapping and scanning by reference image relatively signal image are realized with the hologram lens scanner in the plane of joint FOurier transform is described. An adaptive filtration of spatial frequency signs of input images may be implemented by matrix of rf photodetectors with summarized rf outputs and tunable sensitivity or by computer controlled spatial light modulator placed in images FOurier plane in front of photocathode.
