多路角度复用体全息三维显示技术

摘要

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.%为满足高分辨率真三维大数据显示的空间带宽积要求,提出一种基于多通道角度复用模式的体全息三维显示技术.通过对三维场景进行波前编码,获得相位计算全息图,并将计算全息图依次按照不同角度复用记录到掺杂金纳米颗粒体全息光致聚合物材料的同一区域,获得复用体全息图,再现时可以在不同角度观察三维场景.在体全息三维显示实验系统中,实现体全息材料记录区域的单点像素总数为120×1 920×1 080,显示的空间带宽积达到了2.5×108,相对于空间光调制器显示提升了120倍.
