地面层湍流被认为是占主导地位的大多数望远镜网站。其中一部分是由望远镜圆顶和结构与周围环境的相互作用引起的,导致不同温度下的空气混合,从而导致光学扰动。在这里,我们研究使用空气幕的形式层流空气流,以减少这种混合。我们提供了实验室测量的混合及其缓解的影响,并详细介绍了可以采取的步骤,以减少这种影响。开发了望远镜穹顶结构的应用。
Ground layer turbulence is seen to be dominant at most telescope sites. Some fraction of this is caused by the interaction of the telescope dome and structure with the surrounding environment, leading to mixing of air at different temperatures, and hence, optical perturbations. Here we investigate the use of laminar air flow in the form of air curtains to reduce this mixing. We provide laboratory measurements of the effect of mixing and its mitigation, and detail the steps that can be taken to reduce this effect. Application for telescope dome structures is developed.
