Abstract

A Joint Transform Correlator which uses inexpensive liquid crystal televisions as spatial light modulators has been constructed. The advantages that this architecture offers over the Vander Lugt matched filter type correlator will be examined. The disadvantages shared by both architectures, as well as some constraints unique to the Joint Transform configuration, will also be discussed.
