Abstract

Acousto-optic spectrum analysis is probably the simplest optical signal processing technique with real practical value. A signal applied to an acousto-optic Bragg cell deflects a beam of light onto an array of photodetectors. The detector which is illuminated indicates the signal frequency. The range of bandwidths and resolutions of currently available Bragg cells is well matched to the requirements of laser radar systems, making the technique of interest for laser radar applications. In this paper the acousto-optic spectrum analyser is described and the performance of such a processor is presented.
