Signal processing functions such as convolution, correlation, and Fourier Transformation have been obtained in real-time using the efficient diffraction of laser light from acoustic surface waves progagating on LiNbO3. Different device configurations and detection schemes are discussed. Results are presented for the usual delay-line transducer configuration, as well as for an improved scheme which eliminates the problem of the reflection signal which is associated with this configuration. A discussion is given indicating the extension of the acousto-optical convolver to the generation of ambiguity functions and the correlation of a light amplitude distribution with an acoustic signal.
