Abstract
The Hologram is known that can reconstruct three-dimensional images perfectly. The Computer-Generated Image Hologram (CGIH) is the hologram that is calculated interference phenomenon by computer, and reconstructed image placed near the hologram plane. In our previous study, because of improvement of the output device, it has been possible to output high resolution and refinement CGIH. However, the distortion of the reconstructed image caused by the approximated calculation for high-speed computing has become a serious problem. In previous report, we abolish approximate calculation by fast computation using the GPU, and get the appropriate reconstructed image. In this paper, we improved the Image quality of near the hologram-plane and calculation speed by using optimized the point-source data and made full-color CGIH with proposed method.
