Abstract
The principle and experimental results of a novel spatial bifurcating optical associative retrieval and pattern recognition technique are presented. A single 2D input image is associated with self-amplification with two output images through holographic diffraction in a photorefractive crystal. In an optical experimental setup utilizing a photorefractive crystal BaTiO3, interesting optical edge enhancement, pattern recognition and auto-associative retrieval phenomena have been demonstrated.
