A Novel Compact Parallel Optical Correlator

摘要

We present a compact parallel optical correlator (CPOC) based on joint transform correlation manipulation that can be used for various applications. Two innovative approaches are adopted to make the whole system more compact with a volume of 17×5×3cm~3. Two demo systems, I.e., guidance of guided missile and on-orbit rendezvous and docking have been established. The experimental result showed that CPOC system currently operates at approximately 300 Hz and can accurately determine the positioning information when a 1024×768 pixel spatial light modulator (SLM) is employed.
