Patent ID: 8279507

Claim:
A hologram, which is fabricated by applying Fourier transform to two or more different input patterns to obtain a plurality of corresponding Fourier transform images and arraying said Fourier transform images on the same plane according to a given two-dimensional array principle into a computer-generated hologram, wherein when a plurality of point light sources located behind said hologram are viewed through said hologram, said two or more different patterns are simultaneously and parallel reconstructed in correspondence to array positions of said plurality of Fourier transform images, a first of said two or more different input images being reconstructed at a correspondence to a first of said plurality of point light sources and a second of said two or more different input images, different from said first of said two or more different input images, being reconstructed at a correspondence to a second of said plurality of point light sources, said first image not being reconstructed at the correspondence to said second of said plurality of point light sources.
