摘　　要：在传统的狭缝光栅裸眼立体显示器设计中,在增大可视区域左右尺寸和降低图像间串扰时,将会引起光能损失率增大。针对这一问题,对传统的设计参数进行优化,在确保光能损失率可以接受的条件下,依据立体视觉要求进行仿真和实验,通过减小狭缝宽度的值,增大视区的左右尺寸,降低串扰。实验结果表明,与理论值相比较,优化后的视区左右尺寸增大9 mm,串扰值降低2.3%,而光能损失率只增加0.07,具有较高的应用价值。In the traditional design of naked-eye stereoscopic display based on parallax barrier, the light energy loss rate will increase when increasing the viewing area and reducing the image crosstalk. In order to solve this problem, in this paper, some work is done in optimizing the traditional design parameters. Some simulation and experiment are completed according to the demand of stereoscopic vision while at the same time, ensuring that light en- ergy loss rate is under the acceptable range. Through reducing the slit width and increasing the viewing area, the crosstalk is decreased. The experimen- tal results have shown that the optimized viewing area size have been increased by 9 mm and the crosstalk value have reduced by 2.3%. The light energy loss rate is only increased by 0.07, which has a high value.
