柱面透镜自由立体显示器的分辨率损失研究

Resolution Loss of Autostereoscopic Display Based on Lenticular

在引入分辨率损失的概念基础上,利用光线追迹的方法,通过ASAP软件研究了柱面透镜光栅式自由立体显示器的柱镜光栅导致自由立体显示器分辨率下降的原因。分析了柱镜光栅与LCD显示器之间以不同角度装配时,柱镜光栅对显示图像在垂直和水平方向上分辨率的影响,实验和计算机模拟研究均得出两方向分辨率下降一般是不同的结论,提出了一种立体显示器分辨率损失的评定方法,将对柱镜光栅式自由立体显示器的设计有指导意义。

Resolution loss concept of autostereoscopic display was introduced. By the method of ray tracking, ASAP software was used to analyze the resolution loss of a LCD autostereoscopic display based on lenticular sheet. The resolution loss in horizontal direction and vertical direction were studied at the same time when a lenticular sheet was mounted in front of LCD display with different angle. The experimental and computer simulation showed that the resolution loss in two directions is not the same. And an evaluation method of 3D resolution loss was proposed.
