Abstract
In 1986, the U.S. Army Missile Command (MICOM) unveiled the world's smallest optical correlator to demonstrate the ability to make small rugged optical processors capable of surviving transportation and use outside the laboratory. That capability has now been extended. A new solid block correlator has been built for MICOM by the Optical Corporation of America Applied Optics Division. This advanced solid block correlator (ASBC) is based on the same designed used for the original solid block correlator, but incorporates liquid crystal televisions in both the input and filter planes. The ASBC also has the advantage of two separate filter channels to increase filter throughput or allow simultaneous monitoring to the response to two different filters. This paper will present the results obtained from evaluation tests performed with the ASBC.
