摘　　要：线光源阵列的参数在一维集成成像3D显示器的设计中尤为关键,直接影响一维集成成像3D显示器的分辨率、观看视角以及串扰度。通过对单个线光源及图像元光学模型的分析,根据几何光学原理推导出分辨率和观看视角的计算公式,然后建立基于线光源阵列和微图像阵列的光学模型,深入研究相邻线光源的串扰以及对观看视区的影响,并进一步修正了观看视角公式,并且给出了串扰度公式。研制了该3D显示器的实验样机,实验结果表明:减小线光源的宽度可以提高一维集成成像3D显示器的分辨率和观看视角,同时可以降低该显示器的串扰度。A one-dimensional integral imaging(1DII)3D display based on a linear light source array has high resolution and optical efficiency.The parameters of the linear light source array is one of the most important keys to design the 1DII 3D display.It directly affects the viewing angle,resolution and crosstalk factor of the 1DII 3D display.Based on the analysis of single linear light source and image element optical model,the calculation formulas of resolution and viewing angle were deduced according to the principles of geometric optics.Secondly,an opticle model based on the linear light source array and micro image array was established,and the crosstalk between adjacent linear light sources and its influence on the viewing area were further studied.The viewing angle formula was further modified and the crosstalk formula was given.An experimental prototype of the 3D display was developed.The experimental results show that reducing the width of the linear light source can improve the resolution and viewing angle of the 1D integral imaging 3D display,and at the same time reduce the crosstalk of the display.
