摘要
针对集成成像3D显示观看视场范围小的问题和微透镜之间间隙的杂散光干扰导致的显示质量下降问题,提出了适合柔性显示及曲面显示器的曲面针孔/微透镜阵列结构.采用TracePro光学仿真软件对基于曲面针孔/微透镜阵列的集成成像3D显示的记录和重构过程进行仿真,结果显示:在记录和重构阶段,曲面针孔/微透镜阵列可以有效地减少透镜阵列之间杂散光引起的图像质量变差的问题;当记录和重构阶段均用曲面/针孔微透镜阵列时,记录三维物体的视角大,获得重构图像的视场角也相对较高.采用旋转接收屏法获取不同观看视角下的图像质量,当曲面针孔/微透镜阵列的曲面度数为30°时,重构图像质量最好.
Abstract
Integral imaging 3D display has a small field of view range, and the stray light between the microlens will cause degradation of reconstructed images. In view of these problems, this paper presents a pinhole/ microlens array structure with curved surface, which fits flexible display and curved surface display well. The parametric analysis of curved surface pinholes / microlens array according to the integrated imaging principle conducted, and the recording and reconstruction process of integrated imaging 3D display based on curved surface pinholes / microlens array was simulateed with TracePro. The results show that, in the recording and reconstruction process, the quality of reconstructed image can be improved by the curved surface pinholes / microlens array structure. Concretely, a larger visual angle of three-dimensional objects is obtained in recording process and the field angle of reconstructed image is larger relatively. The quality of reconstructed images are accessed by rotating the receiving screen, and it is found that the best images can be obtained when the curved degree of the curved surface pinholes / microlens array is 30°.
