Resumen:
An image multiplexing technique, based on the internal modulation of speckle grains by using different multiple aperture pupils during exposure, is proposed. A BSO crystal is employed as the recording medium. A theoretical analysis of the multiplexing procedures is outlined. Selective retrieving of each encoded image and the superposition of several images is discussed. Experimental results in connection with image binary operations are presented.
