Abstract : An optical correlator is disclosed that compares signals of interest with selected reference signals stored in holograms. The holograms are arranged so that the selected reference signals impinge onto the plane of the entrance of fiber optics arranged with an optical delay line and fiber optic amplifiers to form a delay line amplifier array. The optical delay line receives the signals of interest represented by light modulated pulses. The cooperative action from the light from the hologram and the light from the optical delay line produces signals that are proportional to the correspondence between the signals of interest and the stored reference signals.
