An 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 ofthe geometric parameters ofthe pupils. Experimental evidences are presented.
