Optical Pattern Recognition using an Optically Addressed Spatial Light Modulator.

Abstract

The purpose of this paper is to discuss the first results of a continuing study on the use of a Spatial Light Modulator in a pattern recognition system. The specific SLM that is being studied was built by Lockheed Missiles and Space Company Inc. of Palo Alto Ca.1 and is on loan to the University of Alabama in Huntsville. This SLM, an optically addressed device, is being used as a spatial filter in a pattern recognition system. The results of a computer study into the most advantageous use of the SLM will be presented as well as the experimental test plan that has been devised from these results.
