Abstract : A high discrimination intensity optical correlation system is presented in this article. By using a lensless special differentiation filter to achieve edge enhancement for the input images, the discrimination of the intensity optical correlator with the Fresnel holographic filter is improved. Theoretical analysis and experimental demonstration are given. (MM)
