Eng. 39(12), 3232-3238 (Dec 01, 2000). ; http://dx.doi.org/10.1117/1.1327496http://hdl.handle.net/10784/1425An alternative image multiplexing technique, employing a multiple-aperture pupil for each exposure, is presented. The aperture arrangement of the pupil is modified between exposures. A thick photorefractive BSO crystal is used as recording material. The technique allows concentrating the spectral components of a pair of images selectively into isolated spots in the Fourier plane. Two applications are proposed, in image processing and optical metrology. © 2000 Society of Photo-Optical Instrumentation Engineers. © 2000 Society of Photo-Optical Instrumentation Engineersenginfo:eu-repo/semantics/articleinfo:eu-repo/semantics/closedAccessOptical signal processingSpeckleCrystalsAcceso cerrado2014-03-26Tebaldi, MyrianTrivi, MarceloBolognini, NéstorÁngel-Toro, LucianoTebaldi, MyrianTrivi, MarceloBolognini, NéstorÁngel-Toro, Luciano10.1117/1.1327496
