Paper Abstract

We present a set of analytical formula on describing the diffraction field of the three dimensional (3D) triangular-meshbased model. The advantage of the proposed method is that it can avoid using the numerical algorithm -- Fast Fourier Transform, which leads to a depth-of-field limitation by the Whittaker-Shannon sampling theorem. We employ the proposed method to generate the hologram of 3D texture model derived from the real scene or 3D design software. In order to further increase the computation speed, we have rendered a real scene by employing the GPU platform. Our homemade GPU algorithm performs hundreds of times faster than those of CPU. As we developed a general phase adjustment technique for polygon-based algorithm, the holographic reconstructed scenes possess high performance.
