摘要: 讨论了双相干点光源的三维空间干涉场的一般数学描述,分析了3个不同截面处的干涉强度的空间分布情况,并给出了相干相长点的计算机模拟图样,该结果也适用于其他类型波的相干叠加场分布。

Abstract: The interference of two point sources is analyzed accurately. The interference pattern and the separation of adjacent bright fringes on different sections are described. And it is found that the separation is the function of the interference order, the wavelength, the source distance, and the observation points. The computer simulation results are given also. These results also work for the interference of other kinds of coherent source.

Key words: interference of point coherent sources, hyperbola family, hyperboloid family, interference pattern, fringe separation
