Resum
In this work we propose a method to obtain single centered correlations with an optical setup based on a jointtransform correlator. 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
