Pattern recognition with a phase-shifting interferometric correlator. Discrimination-capability enhancement

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 met...
