High Resolution Light Field Display Based on Polymer Dispersed Liquid Crystal Films

基于聚合物分散液晶薄膜提出了一种新型高分辨率光场显示方法。首先,搭建虚拟相机阵列,用来对目标物体的光场信息进行采集,从而获得其元素图像阵列;然后,根据聚合物分散液晶的光电特性,通过调节聚合物分散液晶薄膜的外加电压以及利用人眼的暂留/余晖效应,可获得高分辨率的光场显示结果。实验结果表明,相较于传统方法,所提出的方法较为简便,并拥有较高的显示质量,所呈现图像的峰值信噪比提高了约11%。另外,所提出方法搭建的系统难度小,实用性强。

A novel high resolution light field display method based on polymer dispersed liquid crystal film is proposed.First,the virtual camera array is built to collect the light field information of the target object,so as to obtain its element image array.Then,according to the photoelectric characteristics of the polymer dispersed liquid crystal,high resolution light field display results can be obtained by adjusting the applied voltage of the polymer dispersed liquid crystal film and using the transient/afterglow effect of the human eye.The experimental results show that compared with the traditional method,the proposed method is simple and has higher display quality,and the peak signal-to-noise ratio of the presented image is improved by about 11%.In addition,the system built by the proposed method is less difficult and practical.
