Paper Abstract

When a large scale Fourier transform is required, the main disadvantage in the classical architecture for optical Fourier transforiing (froi front to back focal planes of a lens) is its length. If special detectors (CCD caDera), spatial sodulators (light valve) or filters (iiquid crystal iodulator) are to be used, the size of the transfora has to iatch the size of the active eleient of the device. When perforiirig optical correlation, the final length of the set up will be about four times the focal length of the two lenses (if they are equal).
