摘要 根据广义的惠更斯-菲涅耳原理,推导了部分相干涡旋光束在湍流介质中传输时光强分布情况的理论公式,详细研究了部分相干涡旋光束在湍流介质中的传输变化规律。研究结果表明,湍流介质的强弱,光源的相干性以及光束所带拓扑电荷数大小均会影响光束传输特性。 Based on the extended Huygens-Fresnel principle,the propagation formulas for partially coherent vortex beams in a turbulent atmosphere have been derived,then the propagation property of such beam in turbulent atmosphere has been investigated in great detail,the results indicate that the turbulent atmosphere,the spatial coherence and the topological charge play an important role in the beam propagation.
