Paper Abstract

Jet Propulsion Laboratory (JPL) has developed, for the first time, a matchbox-size 512 X 512 grayscale optical correlator (GOC) with the volume of 2 inch X 2 inch X 1 inch. This compact 512 X 512 GOC consists of a pair of newly developed ferroelectric liquid crystal spatial light modulator (FLC SLM) with a 7-micrometers pixel pitch, the smallest feature size developed to date. New system architecture has been designed that has greatly simplified the system alignment and relaxed the tolerance of the Fourier transform lenses. An experimental result of automatic target recognition (ATR) applications using this GOC has been accomplished. The high-quality correlation output has validated the superior quality of the FLC SLM and new GOC architecture.
