| 摘 要： | 文中主要研究发功率激光光学系统光学表面多次反射而形成的杂散光及其数学模型与计算方法，提出了杂散光分析的二叉树数据结构。利用这种数据结构，作者编制了激光光学系统杂散光分析软件，针对两个实例建立了近轴鬼光束树。实例计算表明，采用该数据结构可以全面描述杂散光状况，并根据设计人员的要求捕捉危害较大的鬼像。

| Abstract: | In the paper the mathematical model and algorithm of stray light caused by multi reflection in high power laser systems are discussed,and a data structure of binary tree is presented.The stray light binary tree can be built according to the light transmission paths by allocating RAM space dynamically,and it can be deleted when it is not useful.Using this data structure,stray light analysis software of laser systems is programmed,the examples are given and the paraxial stray light binary trees are built.As a result,using the data structure,all of the stray light in optical systems can be described and the harmful ghosts those are near the key components or with high energy can be picked. |
