Real-time pattern recognition processor using holographic photopolymer and method of use thereof

摘要

We have designed, built and operated an innovative JTOC system utilizing a holographic photopolymer as the square law detector to record the holographic data for one-step correlation signal requisition in real time. The resultant high-resolution, high-speed JTOC is useful to perform real-time pattern recognition. An example application that has been demonstrated is fingerprint verification.
