Paper Abstract

The 5G network has the advantage of ultra-high transmission bandwidth, which will accelerate the developments of new three-dimensional (3D) communication systems. Computer-generated holographic display is an ideal solution for 3D communication because it could provide realistic 3D effect. Currently, only the amplitude of the wavefront, rather than the phase, is recorded by the traditional image capture system, which could not provide 3D information for the 3D computer-generated holographic display. Based on the light-field camera, a capture system employed in the computergenerated holographic display is developed. It could calculate position of every object point, and render the point-cloud model of the target 3D object. The layer-based angular-spectrum method is also employed in this capture system to calculate the computer-generated holograms (CGHs) of the 3D object. Simulations and experiments have verified that the proposed capture system is able to utilize the transmission bandwidth of 5G network. The proposed system realizes quasi real-time output of large size CGHs. The reconstruction quality of these CGHs is preferable. The proposed capture system for 3D holographic communication would have a broad application prospect through further optimizations and developments.
