Abstract
In an optical heterodyne system a first coherent light signal is received on an ordered array of light responsive elements, and a local oscillator source provides a second coherent light signal, the frequencies of the first and second coherent light signals being different. Mixing apparatus is provided to focus the second coherent light signal upon each of the light responsive elements of the array in a preselected sequence, and scanning apparatus scans the light responsive elements in the same preselected sequence to receive light responsive signals generated by the light responsive elements, each of the light responsive signals being related to the intensity of light impinging upon a different one of the light responsive elements and having a frequency equal to the difference between the frequencies of the first and second coherent light signals.
