如何求辐射强度?

      老师您好,有一个问题想要请教。

      以市面上常见的波长 254 纳米、输入功率为30 瓦的紫外线灯为例,在正常工作距离(1米)上,其辐射强度为 90微瓦每平方厘米。这里的辐射强度应该如何计算呢?

      如果我采用一束光线照射一个小球,那么如何求得这个小球所受的辐射量呢?

      你确认是要辐射强度而不是光学强度?前者请找到定义计算,后者参见 

      Ansys Insight: 光学强度、功率、电场强度平方的关系以及电磁能量

      其它你需要先找到计算公式。FDTD给你电场,磁场,然后你再根据定义计算。

      In this example, the units of radiant intensity will be geometry dash 3d Watts per square centimeter (W/cm²). This value tells you the UV power received per second per unit area.

      I removed the unrelated link and close this post.
