  不知道你想要的结果是什么？
  白光做光源对FDTD很简单，只需要指定光源光谱就可以了。正常情况下，你可以得到每个波长（监视器中指定的波长）的干涉场。
  如果你要多波长的干涉场，情况复杂一些，因为监视器中的结果并不给出光的颜色，而是指定波长的场/强度。
  因此，你可以用后续处理得到假彩色条纹，比如根据强度赋不同的颜色；要真彩色的化，可能更复杂。你需要琢磨一下这样将强度结果与色彩联系起来。
  双缝干涉的例子网上有。https://forum.ansys.com/forums/topic/double-slit-experiment/

    孙老师好。我是想仿真Mirau型干涉显微镜所生成的白光干涉图样。一束光在干涉物镜里被分光，一部分照射到样品上，一部分照射到标准平面反射镜上，然后这两束光在像面发生干涉

    另外我印象中FDTD Solutions 好像一次只能仿真一个波长，如果光源是多波长的话貌似会有数值色散现象产生

  干涉可仿真，但是要得到真实色彩，需要更多后续处理，比如可以计算空间任意一点的色坐标。由于网站问题，没法贴链接，你可以在官网上搜Color，Colormatch 等
