| 摘 要： | 光学系统杂光分析对航天航空，精细细微分析领域的光学设计有着重要意义，其首要问题是研究光学系统中典型受光表面的散射模型。该文用小镜面细分非成像表面，结合概率论的方法，在考虑表面遮挡因子的基础上，推导了光学系统训均方粗糙度与光波波长之比〉１．０的非成像表面双向反射分布函数的数学模型，把表面特征参数与表面散射分布显式地联系起来。

| Abstract: | The first problem is to study the model of scattering from typical surfaces in your optical system before stray light is analysed in this paper. On the basis of the little mirror like facets theory, the model, i. e. the BRDF(bidirectional reflectance distribution functions) of non optical surfaces in optical system is given. This model is directly connected with the surface characteristic parameters. Measurement shows the consistent result with the theory. |
