Abstract : Systems which utilize an optical signal to carry information and employ a three-wave heterodyne detector of the type having a cubic response do not require a local optical signal source in the receiving apparatus since the optical signal source in the receiving apparatus since the optical signal as generated provides two optical signal components for the detector's operation. The third signal is supplied by a local microwave oscillator. A high resolution optical wave ranging system having an improved field-of-view is disclosed which uses such a composite signal in conjunction with a pair of three-wave heterodyne detectors. (Author)
