摘　　要：视宁度是现代天文学的一个重要概念。光在传输时受到大气湍流影响而发生闪烁与偏转,即视宁度。在地基大口径望远镜,激光大气传输等方面,视宁度现象对系统的图像质量起到了重要影响。为了对更加深远的宇宙进行探索,进一步围绕宇宙起源、暗物质暗能量等科学目标开展相关研究,对望远镜的分辨率与灵敏度也提出了更高的要求。在激光传输方面,激光通信、卫星遥感以及光学雷达等在大气环境下进行的工作也受到视宁度的影响。因此,如何检测视宁度,成为当前天文领域的重要课题。介绍了目前各类视宁度检测的现状,分析了DIMM、MASS、SCIDAR以及CFD等技术的原理,并在最后进行了总结与展望。Seeing is an important concept in modern astronomy.The flicker and deflection of light caused by atmospheric turbulence during transmission is called seeing.In the ground based large aperture telescope,laser atmospheric transmission and so on,the phenomenon of seeing has an important impact on the image quality of the system.In order to explore the far reaching universe and further carry out related research around the origin of the universe,dark matter and dark energy and other scientific objectives,higher requirements are put forward for the resolution and sensitivity of telescopes.In the aspect of laser transmission,the work of laser communication,satellite remote sensing and optical radar in atmospheric environment is also affected by the seeing.Therefore,how to detect the seeing has become an important topic in the field of astronomical.In this paper,the present situation of various kinds of seeing detection is introduced,and the principles of DIMM,MASS,SCIDAR and CFD are analyzed,and the conclusion and outlook are given at the end.
