Paper Abstract

Optical processing systems have been in existence for over 20 years but few have made the transition from the laboratory environment to the commercial environment. Pattern recognition done with optical correlators is one area which is now showing promise for applications outside the laboratory. Many papers have been written in years past on the need for better and faster spatial light modulators and more efficient filtering schemes prior to commercializing an optical correlator. The current state-of-the-art is now approaching this point. Two companies are even marketing Liquid Crystal Television based correlators. The purpose of this review will be to examine the current capabilities of optical correlators and to match those capabilities to existing requirements.
