ABSTRACT:
An apparatus including a first light modulator for modulating a first light beam with a signal, a second light modulator for modulating a second light beam with a reference signal, first lens means, positioned in an optical path of the second light beam, for introducing into the second light beam horizontal magnification/demagnification which gradually varies with respect to a vertical direction, a beam combiner for combining the first and second light beams, and photodetecting means for detecting the combined light beam received from the beam combiner. The apparatus, thus constructed, is capable of processing the 50 to 100 billion operations per second required for true Doppler (time compression/expansion) processing of SONAR signals.
