| Abstract(in English) | Since a general hologram has a limited viewable area, we usually cannot see the other side of a reconstructed object. There are some holograms that can solve this problem. A disc hologram is well known to be viewable in 360 deg. However, Computer-Generated Disc Hologram (CGDH) requires huge calculation amount. By using CPU, for example, it takes 115.6 hours to calculate a high resolution CGDH (167,936×167,936 pixels). In this paper, to reduce the calculation time of CGDH, we employ Graphics Processing Unit (GPU). Since GPU has many shading unit and parallel processing structure, GPU can work the repetitive process well. As a result, we have achieved that CGDH can be generated at 3.2 hours with high resolution. It is 36.1 times faster than CPU. |
