Abstract

Real-time optical implementation of a logical processor using a joint transform correlator (JTC) is proposed. For illustration, the authors implemented a 4-to-2 encoder using a JTC by spatially encoding the corresponding minterms. Since the use of a single JTC may slow down a logic system with a large number of minterms, a multichannel JTC (MJTC) may be used to speed up the processing. For the MJTC, it was found that four-minterm-based reference images can be used in each channel without significantly deteriorating the system efficiency. Simulation results for both sequential and parallel implementation techniques are presented
