摘要
全息显示技术可以完整记录和再现物体的波前信息,被认为是3D显示的终极目标。其中大视角全息再现是全息显示的关键技术之一。本文从基于液晶空间光调制器的全息显示原理出发,介绍了近年来所出现的多种大视角全息显示方法,并对其实现技术做了探究分析,论证了现有大视角全息显示技术的实现原理及优劣。随着液晶空间光调制器像素间隔的减小、刷新率的提升以及新器件新材料的结合,大视角全息显示必将迎来新的发展。
Holographic display technology can record and reconstruct the wavefront information of the original objects completely,which is considered as the ultimate goal of 3D display.Holographic reconstruction with large viewing angle is one of the key technologies in holographic display.In this paper,several technologies of holographic display with wide viewing angle have been introduced and the technical routes have been discussed by analyzing the principle of the holographic display based on the liquid crystal spatial light modulator.The realization principles,merits and demerits of these existing methods have been analyzed.With the reduction of size of the pixel pitch of liquid crystal spatial light modulators,the improvement of the refresh rate,and the combination of new devices and materials,the wide-viewing-angle holographic display will have new development.
