On-axis joint transform correlation based on the interferometric acquisition of the output plane filters. Labastida i Juan, Ignasi, 1970- Carnicer González, Arturo Juvells Prades, Ignacio Vallmitjana i Rico, Santiago Òptica de Fourier Reconeixement òptic de formes Interferometria Fourier optics Optical pattern recognition Interferometry 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 2019-12-05T08:49:31Z 2019-12-05T08:49:31Z 2000 2019-12-05T08:49:31Z info:eu-repo/semantics/article 0277-786X https://hdl.handle.net/2445/146138 186244 eng https://doi.org/10.1117/12.386859 Proceedings of SPIE, 2000, vol. 4089, p. 425-432 https://doi.org/10.1117/12.386859 (c) Society of Photo-Optical Instrumentation Engineers (SPIE), 2000 info:eu-repo/semantics/openAccess 8 p. application/pdf Society of Photo-Optical Instrumentation Engineers (SPIE) Articles publicats en revistes (Física Aplicada)
