Paper Abstract

In this paper , we real i zed a real -time joint transform correlator .sed on speckle clipping technique using Optic RAM detector and liquid crystal television (LCTV) panels. A basic description of this application is that a time dependent speckle intensity is detected by an Optic RAM detector by which the binarization of 2-dimensional speckle intensity is performed for an arbitrary threshold level of the intensity. Then, the clipped signa] is sent to a LCFV under the control of a microcomiter and, finally, the correlation function of the clipped speckle intensities is obtained based on the joint transfonn correlator (JTC).
