Abstract

High-speed calculation of hologram is very important to realize the continuous real-time holographic 3D-TV. We are studying computer systems and algorithms for the high-speed calculation of hologram. We have proposed three high-speed calculation systems of Fresnel-hologram. But, they didn't come up to real-time holographic 3D-TV when the object is complex. In this paper we have proposed holographic-stereogram calculation system using the graphic-accelerator and the digital-signal-processor (DSP) system. Holographic-stereogram calculation time doesn't depend on complexity of the object. A fast-Fourier-transform of object is calculated fast using the DSP system. We make clear that the continuous real-time holographic 3D-TV will be realized in the near future.
