随着更高的需求和科技发展推动航空飞行器工作速度的提高,航空光学成像的机动、灵活等特点显现更加突出,但实现高质量、高分辨率成像的技术难度也极具挑战性。飞行器与高速气流之间的复杂作用产生气动光学效应,光波或光束经过复杂流场与光学窗口时受到强干扰,为此吸引了众多科学家开展多学科交叉融合的相关研究工作,取得了大量的研究成果,为试验测试和工程实践提供了有力支撑。文中从气动光学流场与光学窗口两方面的计算研究入手,详细综述了气动光学传输效应的研究进展,归纳总结了相应的计算方法,综合当前技术发展趋势给出航空光学成像气动光学传输效应计算研究的思考和建议。

With higher demand and technological development to promote the working speed of aerial vehicles,the mobility and flexibility of aerial optical imaging have become more prominent,but the technical difficulty of achieving high-quality,high-resolution imaging is also extremely challenging.The complex interaction between aircraft and high-speed airflow produces aero-optical effects,and light waves or beams are subject to strong interference when passing through complex flow fields and optical windows,which has attracted many scientists to carry out multidisciplinary cross-fertilization of related research work,and a large number of research results have been achieved,providing strong support for experimental testing and engineering practice.In this paper,starting from the calculation of aero-optical flow field and optical window,the research progress of aero-optical transmission effect is reviewed in detail,the corresponding calculation methods are summarized,and the thinking and suggestions of aero-optical transmission effect calculation for aerial optical imaging are given based on the current technological development trend.
