Dedicated computer for computer holography and its future outlook

Electro-holography is a prospective television technology for realizing photorealistic three-dimensional (3D) movies. However, the enormous computational power requirement for generating computer-generated holo- grams (CGHs) for digitally recording 3D information of the displayed image has been a barrier for the practical application of electro-holography. To solve this problem, our team has developed a dedicated computer for electro-holography, namely Holographic Reconstruction (HORN). HORN is a peripheral board-type computer comprising of field programmable gate arrays (FPGAs) and a PCI-express interface to configure cluster systems. In this paper, we introduced the detailed structure of HORN-8 and the implemented algorithms on it. Moreover, we discuss future prospects for improving its visual performance using executed experimental results.
