摘　　要：半球-圆柱形转塔处非稳态流场所产生的气动光学效应会使光瞳处的激光束发生偏折、抖动和散焦,从而导致机载激光通信系统的光学性能退化。这类负面光学效应呈现出多频率、多模态和分区域的物理特征,给相关研究带来了极大的挑战。为了减轻气动光学效应所带来的负面影响,学者们已对转塔处气动光学效应的产生机制以及相应的流动控制和光学校正展开了研究。本文概述转塔处气动光学效应研究的工程背景和方法框架,并且归纳了气动光学效应研究中所使用的流动/光学仿真方法、实验测量系统,以及光束波前畸变数据的后处理算法。同时也讨论了该研究在数值仿真、实验测量、流动控制,以及自适应光学校正等方面所获得的重要进展和物理认知。最后对转塔处气动光学效应的研究进行了总结,并在未来展望中给出了一些研究参考。The aerooptical(AO)effects generated by the unsteady flow field around a hemisphereoncylinder turret can cause deflection,jitter,and defocus of a laser beam,consequently degrading the optical performance of an airborne laser communication system.These negative effects have multifrequency,multimode,and spacedistributed characteristics,posing significant challenges to research in this area.To mitigate the AO effects around the turret,previous studies have investigated the generation mechanisms of AO effects and the corresponding flow controls and optical corrections.This paper reviews the engineering background and research framework for AO effects around a turret,summarizing the research progress of the flow/optical simulation methods,experimental measurement systems,and postprocessing algorithms for the aberrated wavefront data.Additionally,this paper discusses the major progress and current understanding on the AO effects in terms of numerical simulations,experimental measurements,flow controls,and adaptive optics.Finally,the research progress on the AO effects around the turret is summarized,and some research references are provided for future outlook.
