Abstract
We present a new optoelectronic quasi phase processor based on a conventional joint transform correlator architecture and using a liquid crystal SLM. The phase information is extracted from a joint transform spectrum producing a good correlation performance in terms of noise tolerances and peak sharpness. Several characteristics of the used SLM improving the correlation function are investigated. Computer simulations of the correlator performances and experimental results of an application on tool recognition are presented and discussed.
