摘要

我们提出了部分相干正弦光束的表达式，并推导出这种光束在非科尔莫哥罗夫湍流中的传播方程。我们模拟并分析了非 Kolmogorov 湍流中光束的强度剖面。结果表明，正弦阵列轮廓在传播过程中会被非科尔莫哥洛夫湍流和光束参数破坏，当 a 和 b 设置为正弦时，这种光束的强度轮廓会变成片状。这里介绍的部分相干正弦光束的阵列剖面特性显示了新的特性，这些光束有助于自由空间光通信。

Properties of a Partially Coherent Sine Beam in Non-Kolmogorov Turbulence

We present the expression of a partially coherent sine beam and derive the propagation equations of such a beam in non-Kolmogorov turbulence. The intensity profiles of the beam in non-Kolmogorov turbulence are simulated and analyzed. The obtained results show that the sinusoidal array profile is destroyed by non-Kolmogorov turbulence and beam parameters during the propagation, and the intensity profile of such a beam becomes a sheet, when a and b are set. The array profile properties of partially coherent sine beams introduced here display new properties, and these beams help free space optical communications.
