▲ [6a-A409-4] Simulation of 360-degree Semi-mechanical Table Top Electronic Holographic Display System
キーワード：Holography, Digital holography, Diffraction gratings
Although 3D (3D) holographic displays are considered the ultimate display, the realization of a 3D holographic display is a practical challenge. The table top holographic display system is one of the next generation 3D holographic display systems. Recently, a prototype of the 360-degree holographic table-top display was introduced. This system consists of three digital micromirror device (DMD) for R/G/B colors, 4-f Fourier off axis filtering systems, a parabolic mirror for 3D object and a mechanical motor for time-sequentially displaying 360-degree images on the viewing circumference [1]. The prototype needs to replace the mechanical rotation part with the non-mechanical but equivalent part, which is one of challenges.
In this presentation, we report a design and simulation of semi-mechanical table top holographic display system based on diffractive optics. We design and simulate a diffractive multi-focus grating (MFG). And we are supposed to set up the MFG in the table-top system instead of conventional huge mechanical part. The MFG is based a diffraction optical elements (DOEs), it is designed as a carrier wave that can deliver image information toward the desired direction [2, 3]. The conventional system generates 1,024 holographic multi-views sequentially, but in this study, we propose the semi-mechanical system consist of fewer and debulked mechanical parts.
