【摘要】：热问题贯穿了望远镜设计的各个方面,而且随着望远镜口径的增大,温度对望远镜的工作性能和稳定性的影响也越来越明显。望远镜的主镜作为望远镜系统中关键的光学元件,对望远镜的成像质量有着重要的影响,为了克服主镜视宁度对望远镜成像质量和望远镜主镜温度梯度导致的热变形对望远镜成像质量的影响,对望远镜主镜温度进行合理地控制显得十分的必要和重要。本文结合国外大口径望远镜,详细论述了现代望远镜主镜热控的原则,总结了望远镜热控设计的方法,并进行了相应的探讨,为今后的大口径望远镜的主镜热控设计提供一定的参考价值。
[Abstract]:The thermal problem runs through all aspects of telescope design, and with the increase of telescope caliber, the influence of temperature on the performance and stability of telescope becomes more and more obvious. As the key optical element in the telescope system, the primary mirror of the telescope has an important influence on the imaging quality of the telescope. It is necessary and important to control the primary mirror temperature reasonably in order to overcome the influence of the primary mirror viewing degree on the imaging quality of the telescope and the thermal deformation caused by the temperature gradient of the primary mirror of the telescope. In this paper, the principle of thermal control of modern telescope primary mirror is discussed in detail, the design method of thermal control of telescope is summarized, and the corresponding discussion is made. It provides a certain reference value for the thermal control design of the main mirror of the large aperture telescope in the future.
