Paper Abstract

We present a high-speed compact Binary Phase Joint Transform Correlator system based on a single liquid crystal over silicon spatial light modulator. The system is capable of processing images of 320*120 pixel resolution at frame rates currently limited to around 40 frames per second by the choice of camera within the system. The system is presented in the context of an image comparator system in a fighter aircraft cockpit, which is used to track the view of the pilot. This is achieved by using a helmet-mounted camera to provide the input scenes and some of the inherent properties of the Joint Transform Correlator. Results from an experimental prototype are presented.
