基于柱透镜光栅的虚模式下一维集成成像显示特性

针对柱透镜光栅的分光特性,构建了虚模式下一维集成成像系统的显示平台,对显示分辨率、观看视角和重构图像深度三个表征显示特性的参数进行了系统分析,并在此基础上,提出了一种一维集成成像显示过程中观看视点图像的计算机模拟重构方法,该方法利用光在柱透镜中的传播规律,依次计算观看视点在每个柱透镜中所看到的图像信息并最终合并成一幅视点图像。实验结果表明,计算机模拟重构的视点图像与显示平台的显示效果完全吻合,可以真实描述一维集成成像的显示过程,分析得到的显示特性参数可以作为一维集成成像系统设计的理论依据。

Display characteristics of one-dimensional integral imaging in virtual mode based on lenticular lens array

According to the optical properties of lenticular lens array,we build a virtual image display platform for one-dimensional integral imaging.Then we analyze systematically the display resolution,the viewing angle and the depth of focus,which can describe the display characteristics.Based on this,a novel method is proposed for reconstructing the viewpoint image during the one-dimensional integral imaging display process by computer simulation.According to the laws of light propagation in lenticular lens,the images,seen from some viewpoint,corresponding to every lenticular lens can be obtained and used to make up a viewpoint image using the proposed method.Experiment results show that the obtained viewpoint image can perfectly match that from the display platform and truly describe the one-dimensional integral imaging display process.The obtained parameters of the display characteristics can be used as the theoretical basis when designing one-dimensional integral imaging system.
