推导了部分相干扭转各向异性高斯-谢尔模型(TAGSM)光束在湍流大气中传输的解析公式。详细研究了TAGSM光束在湍流大气中的传输特性。结果表明，在湍流大气中，TAGSM光束将变为圆形光束，低相干性和较大的扭曲对光斑有反圆化作用。相干性越低、扭曲越大或湍流越强，光束光斑扩散越快。
Analytical formulas are derived for the propagation of a partially coherent twisted anisotropic Gaussian Schell-model (TAGSM) beam in a turbulent atmosphere. Propagation properties of a TAGSM beam in a turbulent atmosphere are investigated in detail. It is found that a TAGSM beam will become a circular beam in a turbulent atmosphere, and low coherence and larger twist have an effect of anticircularization of the beam spot. The beam spot spreads more rapidly for lower coherence, larger twist, or stronger turbulence.
