Generation of integrated binary Fresnel hologram for multiple images

This paper proposes a method for representing multiple, three-dimensional images in a single binary digital Fresnel hologram. First, jittered sampling is applied to each image. Second, a Fresnel hologram is generated to represent the sampled images so that each of them will occupy a different area on the focal plane. Finally, the Fresnel hologram is binarized with sign-thresholding. When the binary hologram is illuminated with an on-axis reference plane wave, each source image will be reconstructed at their designated position that is separated from the others. The use of jittered sampling is effective in preserving the shaded region in the images, which otherwise would be lost after the hologram is binarized with sign-thresholding, as well as suppressing the aliasing images.
