狭缝光栅1维集成成像3D显示器的狭缝孔径宽度对性能参数的影响

狭缝光栅的参数设计是一维集成成像3D显示器结构设计的关键之一。为了分析狭缝孔径宽度对显示器性能参数的影响，首先根据几何光学推导出分辨率的计算公式以及单个狭缝的观看视角与狭缝孔径宽度的关系，然后根据图像元串扰度推导出狭缝光栅的观看视角的计算公式，并研制了一维集成成像3D显示器原型样机，通过实验验证了减小狭缝孔径宽度可以增大显示器的分辨率和观看视角。该结论对设计基于狭缝光栅的一维集成成像3D显示器具有指导意义。

Effect of Aperture Width on Performance Parameters in One-dimensional Integral Imaging 3D Display Based on Parallax Barrier

A parameter design of parallax barrier is one of the most important keys to design a one-dimensional integral imaging (1DII) display based on parallax barrier. To analyze the effect of aperture width on performance parameters in 1DII display, the relationship between the aperture width and the viewing angle of a single slit was deduced and the calculation formula of the resolution was obtained through geometrical optics. According to elemental image crosstalk factor, the calculation formula of the viewing angle of the 1DII display based on parallax barrier was deduced. A prototype of the 1DII display based on parallax barrier was developed, and the experiment results showed that the resolution and the viewing angle of the 1DII display were increased by decreasing the aperture width of the parallax barrier. The conclusion provides a direction for the design of 1DII display based on parallax barrier.
