Paper Abstract

The acousto-optic correlator is a well developed tool for performing pattern recognition. By cascading several one-dimensional correlators in parallel, it is possible to implement two- dimensional image correlation using only one acousto-optic device. We review the development of acousto-optic correlation and pattern recognition systems, and describe recent developments which have made image correlation practical. Computer simulations of image correlation and modifications to the existing architectures are discussed.
