多束非相干光迭加后光强分布的一点讨论

A Discussion on light intension's Distribution when Many Beams of Non-coherent Light were overlapped

本文利用光的迭加原理,运用矢量合成的方法,推导出多束非相干光的合振幅,合光强计算公式,从而帮助学生加深对光的相干迭加和非相干迭加的理解。

With the help of light's overlapping principle and vector resultant method, the res-ultant amplitude of many beams of non-coherent light intension's caculation for-mula can be infered so as to help the students de?pen their tnd?rstanding of the coherent light overlapped and non-coherent light overlapped.
