Abstract
A total of 300 templates were stored as angularly multiplexed transmis sion holograms at multiple spots on a photopolymer disk. A novel corre lator architecture is described and demonstrated that correlates all t he templates against an input image within one disk rotation (approxim ate to 20 ms). The projected performance of the system is 150,000 temp lates per disk and a processing rate of approximately 6000 correlation s per second.
