Abstract
An alternative image multiplexing technique, employing a multiple-aperture pupil for each exposure, is presented. The aperture arrangement of the pupi l is modified between exposures. A thick photorefractive BSO crystal is use d as recording material. The technique allows concentrating the spectral co mponents of a pair of images selectively into isolated spots in the Fourier plane. Two applications are proposed, in image processing and optical metr ology. (C) 2000 society of Photo-Optical Instrumentation Engineers. [S0091- 3286(00)02712-4].
