Three-dimensional TV using holographic stereogram

Computer holographic stereogram (CHS) is useful for holographic 3D TV because it is constructed from the multi horizontal viewpoint plane images and is compatible to the multi camera stereoscopic image. Each hologram is recorded as a slit hologram (element hologram) but total viewing area and the number of the element holograms have been limited to some extent by the size and the resolution points of LCD. Therefore we used two LCDs for CHS and arranged them horizontally and increased the viewing points to two times and considered how viewing area and reconstructed images of CHS were improved.
