Color laser holographic display of virtual 3D scene

In this paper, a new method, which synthesizes the technology of computer graphics (CG) and holographic integral photography, is proposed to realize the holographic display of virtual 3D scene in large size. In this method, elemental stereographic images of 3D scene are computed by a virtual holocoder instead of using pickup process. And then, the color of elemental stereographic images is separated by computer and three tricolor elemental image series are printed by high graphics printer. The printed image series can be integrated into the previous 3D scene with a lens array whose optic parameters match to the virtual holocoder. If the image series are illuminated by laser, the virtual 3D scene is reconstructed by coherent light, and then the reconstructed scene can be recorded by single wavelength color holographic technology in large size.
