A composite hologram to reconstruct a three-dimensional object is synthesized with a computer using the technique of holographic stereogram. In the first step of the method, a sequence of perspective projections of the three-dimensional object is calculated, and their Fourier transform holograms are also generated with a computer. These holograms are assembled into a final hologram in the second step. This method requires a computation time far less than the conventional method of producing a computer-generated hologram and makes it possible to reconstruct an image with a wide view angle. Some characteristics of the reconstructed image are described, and optimum parameters for the synthesis and reconstruction process are discussed. Finally, an experimental example is presented.
