Recently, the development of computer technologies and new algorithms have made it possible to create brilliant synthetic holograms.1–6 These holograms, whose dimensions can exceed 4 billion pixels, optically reconstruct true spatial images that give continuous motion parallax both in horizontal and vertical directions without any additional equipment such as polarizing eyeglasses. The reconstructed spatial images provide almost all depth cues such as dispersion, accommodation, occlusion, and convergence. Thus, the computer holograms give viewers a strong sensation of depth that has not been possible for conventional 3D systems providing only binocular disparity. Unfortunately, these computer holograms cannot be reconstructed by current video devices such as liquid crystal displays because of their extremely high definition. However, the high-definition holograms presage the great future of holographic 3D displays beyond Super Hi-Vision.
