摘要: 相干性是激光束的一个重要特性, 具有低空间相干性的激光束称为部分相干光束; 关联结构(函数) 是部 分相干光束的一个特有参量, 通过调控相干性可构建具有特殊关联结构的部分相干光束。在湍流大气中, 特殊关 联结构部分相干光束不仅展现出诸多奇特传输性质, 而且能够进一步有效抑制大气湍流引起的光强及相干度分布 退化、光斑漂移和光强闪烁等各种湍流负面效应, 在自由空间光通信、激光雷达和激光遥感等方面有重要应用前 景。近年来特殊关联结构部分相干光束大气传输研究受到越来越多学者的关注。回顾了特殊关联结构部分相干 光束大气传输研究方法和发展历程, 举例展示了厄米系列特殊关联结构部分相干光束的大气传输研究成果。

Abstract: Coherence is an important property of laser beam, and laser beam with low spatial coherence is called partially coherent beam. Coherence structure is an unique parameter of partially coherent beams, and partially coherent beams with special coherence structure can be generated by manipulating their coherence properties. Partially coherent beams with special coherence structure not only exhibit many interesting propagation properties, but also can suppress the negative effects of atmospheric turbulence, such as degradation of intensity and coherence distribution, beam wander and scintillation, which have many application prospects in free-space optical communications, remote sensing, active laser radar systems, and so on. Recently, more and more attention is being paid to the propagation of partially coherent beams with special coherence structure in turbulent atmosphere. The research methods and development of partially coherent beams with special correlation structure are reviewed, and the propagation properties of partially coherent beams with Hermite series coherence structure in turbulent atmosphere are illustrated as examples.

Key words: atmospheric optics, turbulence resistance, generalized Huygens-Fresnel principle, coherence structure, partially coherent beam
