Abstract

A high-resolution full-parallax computer-generated hologram (CGH) is created to reconstruct a photorealistic threedimensional (3D) scene. Fully-computed holographic stereogram is introduced to generate the CGH, which integrates physically based method and holographic stereogram based method to produce accurate depth information as well as view-dependent effects. Accurate accommodation cue and occlusion effect can be created, and computer graphics rendering techniques can be employed in the CGH generation to enhance the image fidelity. A high-resolution hologram with 400 million pixels is fabricated by a lithography system, and the viewing angle is above 30 degrees during optical reconstruction.
