A MULTICHANNEL JOINT TRANSFORM CORRELATOR

Optical correlation has profited from simultaneous advances in spatial light modulators and algorithms, which have considerably broadened it s field of applications. Nevertheless, in many image processing tasks, multiple correlations are required. Optical multichannel correlation architectures have been proposed in the case of classical Vander Lugt correlators. We suggest a solution based on the joint transform correl ator architecture. We show that this solution is well suited to the us e of silicon backplane spatial light modulators involving variable pix el fill factor designs.
