Multimode field correlations are evaluated in atmospheric turbulence. High order field correlations are special cases of the results that we obtained in this paper. Field correlations are presented for various numbers of multimodes, various multimode contents of the same number of modes, and various high order modes versus the diagonal distance from various receiver points, source size, link length, structure constant, and the wavelength. Our results will be of help especially in the design of heterodyne systems operating in turbulent atmosphere and fiber coupling efficiency in systems employing multimode excitation.
在大气湍流中评估多模场相关性。高阶场相关性是我们在本文中得到的结果的特例。本文给出了不同数量的多模、相同数量的多模的不同多模含量以及不同高阶模式与各种接收点、源尺寸、链路长度、结构常数和波长的对角线距离的场相关性。我们的结果将特别有助于设计在湍流大气中工作的外差系统和在采用多模激励的系统中的光纤耦合效率。
