This approach is a modification of a previous procedure that required displaying devices witha full 2irphasemodulation. The displaying requirements are less restrictive than before, allowing the use of manymodulators and configurations. This new method is based on a binary power spectrum and it needs an interferometricprocess to obtain a single detection peak. To validate our new procedure, we propose an optical setupand we presentthe experimental results achieved Òptica de Fourier Reconeixement òptic de formes Interferometria Fourier optics Optical pattern recognition Interferometry On-axis joint transform correlation based on the interferometric acquisition of the output plane filters.
