Evaluation of Transmission Performance for Streaming CGH Video based on Computer Holography and Electro-Holography

Holography is an ideal three-dimensional display technology, and it can reconstruct natural-looking three-dimensional objects with sufficient depth. In this paper, we propose a system model that uses computer holography and electro holography to stream holographic videos. The holographic video is generated by synthesizing computer-generated holograms calculated by using light waves from a virtual object designed on a computer. The holographic video is streamed from a transmitter to a receiver with display devices via networks, and three-dimensional objects are optically reconstructed by using electro-holography with a spatial light modulator. The transmission performances of streaming holographic video over wired LAN (1000BASE-T), wireless LAN (IEEE 802.11ax), and local 5G network were evaluated.
