Abstract
Optical correlation has profited from simultaneous advances in spatial light modulators and algorithms, which have considerably broadened its field of applications. Phase only filters and binary phase only filters present an obvious interest regarding their implementations on existing spatial light modulators. Ferroelectric liquid crystal spatial light modulators are the faster examples. Nevertheless, in many image processing tasks, multiple correlations are required. Optical multichannel correlation architectures have been proposed in the case of conventional Vander Lugt correlators, but few have been realized. We propose and implement a solution for a four channels binary phase only matched filter. We show that this solution is well suited to the use of an electrically addressed Ferroelectric spatial light modulator in the Fourier plane.
