We have developed prototype of a compact optical correlator for video copyright protection that integrates the optical correlation technology used in FARCO (Fast Recognition Optical Correlation) and a holographic storage system. Using the ability of parallel transformation as optical holographic memory, the recognition rate can be vastly improved. In addition, large capacity of optical storage allowed us to increase the amount of reference database. Using its rapid processing capability, a robust recognition system can be constructed by registering video image data. We expect that this optical correlation system is simple and energy-saving, and provides ultrahigh speed system compared with conventional server. This system enables use of an image search system in various fields where it has not previously been possible to use such systems.
