摘要: A Fraunhofer computer-generated hologram (CGH) is proved to be valid in display for three-dimensional (3D) objects from the Fresnel far-field region without a Fourier lens reconstruction. To quickly compute large and complicated 3D that consist of slanted diffused surfaces region, Fraunhofer-based analytical approach using basic-triangle tiling diffuser developed. Both theoretical experimental results reveal CGH can perform same effects as but require less calculation time. Impressive solid are achieved region.
