SPIE 3749, 18th Congress of the International Commission for Optics, 358 (July 19, 1999); doi:10.1117/12.354786; http://dx.doi.org/10.1117/12.354786http://hdl.handle.net/10784/4238An image multiplexing method based on the internal modulation of speckle grains by employing different multiple aperture pupils for recording is proposed. The interferometric fringes profile and visibility in the Fourier plane, for uniform in-plane displacement double- exposed specklegrams through different pupils recording, are analyzed in terms of the geometric parameters of the pupils. Experimental evidences are presented.eng© (1999) COPYRIGHT SPIE--The International Society for Optical Engineering.
