High Quality Content by WIKIPEDIA articles! Optical heterodyne detection is an important special case of heterodyne detection. In heterodyne detection, a signal of interest at some frequency is non-linearly mixed with a reference "local oscillator" (LO) that is set at a close-by frequency. The desired outcome is the difference frequency, which carries the information (amplitude, phase, and frequency modulation) of the original higher frequency signal, but is oscillating at a lower more easily processed carrier frequency.Optical heterodyne detection has special characteristics and special problems that distinguish it from conventional RF heterodyne detection. While an old technique, key limiting issues were solved only as recently as 1994 with the invention of synthetic array heterodyne detection.
