Holography, which was invented by Dennis Gabor, is widely known as the ultimate three-dimensional (3D) technique for faithfully recording and reconstructing 3D objects. A computer-generated hologram (CGH) is the digital interference fringe calculated by a computer. It may be possible to apply electroholography to 3D television (TV)[3–5] because it can reconstruct animated 3D images by sequentially displaying CGHs on a spatial light modulator (SLM). However, in such a system, calculating the CGH is computationally prohibitive. Realizing 3D TV using electroholography requires high-performance computational power.
