In this paper, the method of random wave vectors for simulation of atmospheric turbulence is extended to 2D×2D space to provide spatial degrees of freedom at both input and output planes. The modified technique can thus simultaneously simulate the turbulence-induced log-amplitude and phase distortions for optical systems with extended sources either implemented as a single large aperture or multiple apertures. The reliability of our simulation technique is validated in different conditions and its application is briefly investigated in a multibeam free-space optical communication scenario.
在本文中，用于模拟大气湍流的随机波矢量方法被扩展到二维×二维空间，以在输入和输出平面上提供空间自由度。因此，改进后的技术可以同时模拟具有扩展源的光学系统的湍流引起的对数幅度和相位失真，这些扩展源可以实现为单个大孔径或多个孔径。我们的模拟技术的可靠性在不同条件下得到了验证，并在多光束自由空间光通信场景中对其应用进行了简要研究。
