Paper Abstract

A new photorefractive joint transform correlator architecture using a photorefractive crystal as a reference image storage or sequentially image updating device instead of a joint transform power spectrum recording element is proposed. Three novel and simple methods for moving target recognition and tracking with this architecture are introduced: (1) correlation with single fixed reference image; (2) correlation with a fixed synthetic reference image; (3) adaptive correlation with a sequentially updated reference image. Some specific considerations concerning the recording-erasing property of the crystals and the principle of adaptive tracking are analyzed and discussed. Preliminary experimental studies are made to verify the effectiveness of these methods, the results are in full agreement with our theoretical expectations.
