We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

自然光? 它意味着宽谱和非相干非偏振。你首先要指定光谱范围，再做两个或者三个偏振光源仿真，最后强度/功率量做平均。参见

一般没必要选择比例，因为线性光学范围内结果是线性的，你可以做后续处理，一般不可以同时用三个这样的光源，除非是三个单色光（并非你设置三个单波长光源那样简单，因为此时仍是宽谱入射），否则归化会出问题。参见
