Abstract
A real-time optical joint transform correlator for displacement or velocity measurement in speckle applications is described. The successive patterns from a light scattering object before and after the displacement pass through a ferro-electric liquid crystal (FLC) polarization switch and a birefringent plate. The joint pattern is take by a FLC spatial light modulator (SLM) as a doubly exposed pattern. The joint transform correlation (JTC) is optically calculated from the joint pattern.
