In a previous study, a disk hologram made from a CGH was achieved. The calculation amount of the proposed hologram is approximately a quarter of that of a CGCH. In addition, the viewing zone depends on the hologram size the maximum size of the fringe pattern is decided on the basis of the special frequency of the output device. Because the output device lacks spatial resolution, the hologram cannot provide a large diffraction angle. However, there are just a few reports about creating a disk hologram by use of a CGH. Since a regular disk hologram is a flat reflective type, the reconstruction setup is easy. In contrast, a disk-type hologram is well known as a 360 deg viewable hologram. The CGCH has a special shape that is difficult to construct and calculation of such a hologram takes too much time. Therefore, we propose a computer-generated cylindrical hologram (CGCH) to obtain a hologram with a 360 deg viewable area. ![]() Since a general flat format hologram has a limited viewable area, we usually cannot see the other side of the reconstructed object. ![]() We have been investigating disk holograms made from a computer-generated hologram ( CGH). ![]() Yamaguchi, Takeshi Fujii, Tomohiko Yoshikawa, Hiroshi Disk hologram made from a computer-generated hologram.
