Abstract
The method consists of computing (E-E) a set of two-dimensional images in a three-dimensional geometrical space representing a virtual object from respective different viewpoints. The virtual object is represented by digital data stored in a computer. Holograms are computed (E-E) for the respective two-dimensional images using a fast complex transform, such as a Fourier transform. The holograms are then juxtaposed (E) to form a digital hologram of the object which is physically reproduced (E) by a spatial light modulator. A three-dimensional image of the object is obtained by illuminating the spatial light modulator with a coherent source.
