Abstract

We study an experimental setup to perform pattern recognition by correlation methods. This setup implements the Pure Phase Correlation (PPC) method, let us say, it only takes into account the phase distributions of the Fourier transform of the scene and the target. An experimental study of a PPC method is presented. A phase measurement interferometric technique is used to extract the phase of the Fourier transform of the correlation function. Some aspects related to the intermodulation are examined. Experimental PPC with improved discrimination capability obtained with binary masks is also considered. The experiments are carried out with segmented scenes and with multiobject scenes.
