ABSTRACT:
A two PROM coherent optical processing system under computer control provides zoom of the input object, rotation of the filter PROM relative to Fourier transform of the coherent light image, serial painting of the spatial filter on the filter PROM using a digitally controlled laser scanner, and greater operator control of the filtered image using a digital video processor and the associated computer.
