双相干点光源的空间干涉

摘要

In order to further study the field distribution of spatial interference of two coherent point sources ,a generally expanded mathematical formula of light field and the origins of interference fringes in various shapes were given theoretically .The reasons of why the interference fringes were hard to be observed was provided and the computer simulated figures of the intensity distribution was draw n .%为深入研究双相干点光源空间干涉的光场分布情况，通过理论推导给出了三维坐标空间下光场的一般数学展开式及各个形状干涉条纹的成因，并给出了实验不易观察的干涉条纹的原因和强度分布的计算机模拟图。
