Abstract
The invention relates to a hologram that enables two or more different images to be simultaneously reconstructed even in a state where the hologram is fixed in terms of relative position with respect to an eye, and a holographic viewing device that incorporates it. The hologramis fabricated by applying Fourier transform to a plurality of input image to obtain a plurality of corresponding Fourier transform images--and arraying the Fourier transform images--on the same plane according to a given two-dimensional array principle into a computer-generated hologram. When a plurality of point light sourcestolocated behind the hologramare viewed through the hologram, a plurality of images are simultaneously and parallel reconstructed () in correspondence to the array positions of the plurality of Fourier transform images.
