Paper Abstract

In this paper we report the measurements of the optical absorption spectrum , diffraction efficiency, recording sensitivity , erasure behavior in the poled single crystals LiNb03 with Pr and with Ce and Fe as new impurities respectively, We show associative holographic analog to the Hopfield neural network model in algorithm and present a real-time parallel optical associative memory system implemented with a CeiFesLiNb03 crystal as recording medium and a Fe,LiNb03 crystal amplifier to provide feedback, threshotding and gain . In our experiment, the retrieval of complete image when only a partial image addresses the system is demonstrated.
