A numerical wave optics approach for simulating a partial spatially coherent beam is presented. The approach involves the application of a sequence of random phase screens to an initial beam field and the summation of the intensity results after propagation. The relationship between the screen parameters and the spatial coherence function for the beam is developed and the approach is verified by comparing results with analytic formulations for a Gaussian Schell-model beam. The approach can be used for modeling applications such as free space optical laser links that utilize partially coherent beams.
提出了一种用于模拟部分空间相干光束的数值波动光学方法。该方法包括对初始光束场应用一系列随机相位屏，并对传播后的强度结果进行求和。推导了屏参数与光束空间相干函数之间的关系，并通过将结果与高斯谢尔模型光束的解析公式进行比较来验证该方法。该方法可用于对诸如利用部分相干光束的自由空间光激光链路等建模应用。
