A new type of optical processor is described, and experimental performance data are presented in the form of ambiguity diagrams for various types of signal. The processor uses an ultrasonic light modulator with two electrical inputs and a simple optical arrangement which is relatively easy to align. The ambiguity diagrams are available in real time as light patterns, but the system may be adapted for other modes of operation.
