Abstract

High level image processing and pattern recognition tasks require multiple correlations. So multichannel correlators are of interest. Some architecture configurations have been presented for the Vander-Lugt architecture, but few have for the JTC. We present the experiments concerning two multichannel JTC architectures and compare some of their performances. One is based on the use of spatial light modulators with partially filled pixels, in the second Dammann gratings were used.
