In this paper, we developed an optical model describing the behavior of light at the surface of a slanted lenticular array for autostereoscopic displays in three dimensions and simulated the optical characteristics of autostereoscopic displays using the Monte Carlo method under actual design conditions. The behavior of light is analyzed by light rays for selected inclination and azimuthal angles; numerical aberrations and conditions of total internal reflection for the lenticular array were found. The intensity and the three-dimensional crosstalk distributions calculated from our model coincide very well with those from conventional design software, and our model shows highly enhanced calculation speed that is 67 times faster than that of the conventional software. From the results, we think that the optical model is very useful for predicting the optical characteristics of autostereoscopic displays with enhanced calculation speed.
在本文中，我们开发了一种光学模型，用于描述倾斜柱状透镜阵列表面光在三维自动立体显示器中的行为，并在实际设计条件下使用蒙特卡罗方法模拟了自动立体显示器的光学特性。通过光线对选定的倾斜角和方位角来分析光的行为；发现了柱状透镜阵列的数值像差和全内反射条件。从我们的模型计算得到的强度和三维串扰分布与传统设计软件的结果非常吻合，并且我们的模型显示出极高的计算速度提升，比传统软件快67倍。从结果来看，我们认为该光学模型对于以更高计算速度预测自动立体显示器的光学特性非常有用。
