Paper Abstract

In this paper, we present a newly developed hybrid multi-channel real-time pattern recognition system. Two modified commercial liquid crystal televisions are applied as a real-time incoherent to coherent image transducer and a device to produce converging wavelets with different focal positions. Taking advantages of the cross-grating nature of the LCTV screen, a multi-channel correlator becomes possible. This hybrid system has both the high processing speed of an optical system and the flexibility of an electronic system.
