Volume holographic display technology based on angular multiplexing

To satisfy needs of high resolution three-dimension(3-D) display for big data, an angular multiplexing based volume holographic display technology is proposed. Wavefront of 3-D scene is encoded as computer-generated holograms. Holograms are recorded in gold nanoparticles doped photopolymer with angular multiplexing. With recorded holograms, 3-D scenes could be viewed at different angles. In volume holographic three-dimensional display experiment system, total number of single-point pixels in volume holographic material recording area is 120×1 920×1 080, and spatial bandwidth product is 2.5×10⁸, which is 120 times higher than that of spatial light modulator.
