Abstract

The applications of the joint transform correlator are partly limited by the information loss of the power spectra while being detected and transmitted by conventional detectors and electrically addressed spatial light modulators. The re-writable diarylethene films, which used to be mainly used in optical storage, are successfully tried to detect and transmit the power spectra of the joint transform correlator instead of the CCDs and the electrically addressed spatial light modulators. According to the experiment results and the corresponding comparisons and discussions, the re-writable diarylethene films can be used to detect and transmit the power spectra of the joint transform correlator better than the CCDs and the electrically addressed spatial light modulators in the case of decreasing the information loss. With high resolution and large dynamic range, besides optical storage, the re-writable diarylethene films will be widely used in optically addressed spatial light modulators if the operation period can be shortened remarkably.
