为了定量研究光栅倾斜角度和串扰之间的关系，进而寻求适合的最佳倾斜角度，利用光路方程建立了串扰与光栅倾斜角度的仿真模型，同时对屏前3维空间内的水平方向和垂直方向的串扰进行了仿真。结果表明，光栅倾斜角度增加时，水平视区呈线性下降，而垂直方向视区变化趋势并非线性减少，而是呈阶梯状降低，对这种现象进行了合理的理论解释，得到了光栅倾斜角度和串扰之间的定量关系。该研究结果对设计倾斜光栅式自由立体显示器具有指导意义。

In order to study the relationship between tilted angles of parallax barriers and crosstalk quantitatively and seek for the best tilted angle, a simulation model for crosstalk and tilted angles was established based on the optical path equation. Meanwhile crosstalk in front of the screen was simulated in vertical and horizontal directions respectively. The results show that the viewing zone in horizontal direction decreases linearly, however the viewing zone in vertical direction is not in the same case but decreases step by step. Theoretical explanation of the phenomenon was put forward and the quantitative relationship between tilted angle of parallax barrier and crosstalk was obtained. The study would provide a significant guidance for auto-stereoscpoic display based on slanted parallax barrier.
