对多视点自由立体显示的串扰成因进行了分析，推导出了无串扰观看点与光栅参数之间的关系；然后分别对垂直于显示器方向和平行于显示器方向的串扰进行了分析与计算，得到了屏前三维空间的串扰分布情况.仿真结果表明，沿显示屏幕垂直方向的视区范围大于水平方向的视区范围，而且在水平平行于屏幕的方向上，每一个视点存在多个理论无串扰观测点，但在垂直于屏幕方向上，每个视点只存在一个理论无串扰观测点.最后通过对屏前三维区域视点光强进行仿真，进一步验证了串扰计算的准确性，为自由立体显示系统的最佳设计与具体实现奠定了仿真基础.

The cause of crosstalk based on multi-view autostereoscopic display was analyzed. The relation between sweet spots and parallax barrier parameters was deduced. Then, analysis of the model of crosstalk was processed respectively in vertical and horizontal directions to the flat-panel displays, which aimed to obtain the distribution characteristics of crosstalk in three-dimensional space before the screen. The simulation results show that viewing zone in vertical direction along the screen is greater than it in horizontal direction. And, each view has multiple observation points without any crosstalk in a horizontal direction parallel to the screen, but in the direction perpendicular to the screen, each view has only one such point. Through the simulation analysis of viewing zone, the accuracy of the crosstalk calculation was further validated. The research results of this paper establish a simulation basic platform for the optimum design and concrete realization of autostereoscopic display system.
