视角增大的集成成像3D显示系统

本文设计了一个视角增大的集成成像3D显示系统.该显示系统由显示屏、一列凸微透镜阵列、一列凹微透镜阵列及两列正交偏振片阵列组成.显示屏用来显示微图像阵列，偏振片阵列用来消除相邻图像元之间的串扰，两列微透镜阵列用来再现3D像.本文所设计的集成成像3D显示系统中图像元经过凸透镜所成像的节距影响视角大小，由于像的节距大于图像元的节距，所设计显示系统的视角大于传统集成成像的视角.本文给出了视角理论分析的仿真实验验证，实验结果与理论分析一致

Integral image 3D display system with enhanced viewing angle

An integral image 3D display system with enhanced viewing angle is designed. This system consists of a display panel, a convex micro lens array, a concave micro lens array and two orthogonal polarized sheets arrays. The display panel is used to display elemental image array, the two orthogonal polarized sheets arrays are used to eliminate the crosstalk between near two elemental images. Two micro lens arrays are used to construct the 3D image. In the designed display system, the viewing angle is related to the pitch of the image of the elemental image formed by convex micro lens, as the pitch of the image is bigger than the pitch of elemental image, the viewing angle of the designed system is bigger than that of the conventional integral image. At last, experimental results which agree well with the theory are given.
