Abstract

A new solid block correlator has been built for the U.S. Army Missile Command by OCA Applied Optics. This Advanced Solid Block Correlator (ASBC) is based on the same design approach useful for the original solid block correlator. The ASBC provides both improved performance and a vehicle for evaluating the recently available Liquid Crystal Televisions as spatial light modulators (SLMs). Performance is significantly enhanced by: (1) real-time programmable filter capability, (2) improved SLM speed, and (3) improved SLM uniformity. Furthermore, the ASBC also has the advantage of two separate filter channels to increase filter throughput or allow simultaneous monitoring of the response to two different filters. This paper will present the results obtained from initial tests performed with the ASBC.
