摘　　要：该文以杨氏双缝干涉装置为例研究光场的空间相干性,指出了光源的线度与光场的空间相干性之间的关系,并根据杨氏双缝干涉理论借助Matlab编程进行了计算机虚拟仿真。所得仿真结果与理论推导完全一致,因此,该虚拟仿真为光学理论与实验教学提供了有效的辅助手段。This paper studies the spatial coherence of light field by taking Young’s double slit interference as an example,and points out the relationship between the light sources dimension and the spatial coherence of light field.It also performs computer virtual simulations by Matlab program according to the theory of Young’s double slit interference.The simulation results completely agree with the theoretical analysis,therefore,the virtual simulation provides effective auxiliary ways for the theory and experiment teaching of optics.
