摘　　要：光栅结构是狭缝光栅式LED自由立体显示系统的核心部分.为了进一步提高狭缝光栅式LED自由立体显示系统的性能,提出了一种交错阶梯狭缝光栅结构设计方法.Tracepro仿真实验表明交错阶梯狭缝光栅能够有效分离不同视点图像,适用于构建狭缝光栅式LED自由立体显示系统.实验结果进一步证实:在莫尔条纹弱化方面,交错阶梯狭缝光栅优于阶梯狭缝光栅;在视点图像间串扰抑制方面,交错阶梯狭缝光栅优于传统倾斜狭缝光栅.The structure of parallax barrier is the key part of parallax barrier LED autostereoscopic display system.A new staggered step parallax barrier was designed to improve the performance of parallax barrier LED autostereoscopic display system.Simulation results by Tracepro software show staggered step parallax barrier can effectively separate images from different viewpoints,and fit to the setup of parallax barrier LED autostereoscopic display system.Experimental results also verify that staggered step parallax barrier can balance the Moire fringe minimization and suppression of the crosstalk of images from different viewpoints.With respect to Moire fringe,the performance of staggered step parallax barrier is better than that of traditional step parallax barrier.With respect to crosstalk suppression,the performance of staggered step parallax barrier is better than that of slanted parallax barrier.
