N2 - A system of two separated computer-generated holograms termed digital correlation hologram (DCH) is proposed and demonstrated. In each hologram a different computer-generated complex function is coded. The reconstructed image is obtained as a result of a spatial correlation between the hologram's two parts. The correlation between the two sub-holograms is implemented on a modified joint transform correlator. When the double-elements hologram is displayed on the correlator input plane, and illuminated by a plane wave, a desired image is constructed on part of the output plane. Experimental results are shown and possible applications of the DCH are discussed.
