摘要
意在实现高分辨率成像的新型天文望远镜对天文视宁度提出的更高的要求。本文从湍流介质中的成像理论出发,论述了视宁度的现代定义、湍流的层状结构和选址策略;简要介绍了现代天文选址中视宁度的测量。
New generation telescopes which aim at high resolution imaging of astronomical objects, are putting higher and higher demanding upon the astronomical site with excellent astronomical seeing. Based on the theory of imaging in the turbulent medium, this paper discusses the modern definition of the seeing and the stratified structure of the turbulence as well as the strategy of the site testing. In addition, the measurement of seeing in modern astronomical site testing is introduced briefly.
