Paper Abstract

Real-time spatial domain image correlation and convolution were first demonstrated by White and Yariv using four-wave mixing in photorefractive nonlinear materials, but the full three channel input capability has not been exploited. We report experimental studies showing the application of the third input channel for composite pattern recognition and real-time spatial filtering of correlations or phase conjugate images. Potential applications are discussed for programmable image comparison, optical transformations to solve rotation and scale variance, and an all-optical cellular automaton computer.
