Abstract

地基太阳望远镜及周边设施在观测运行时被太阳辐射加热,发热表面加热望远镜光路附近的空气形成近表面空气湍流,进而引起像质衰减。改善近表面大气湍流的主要方法是抑制太阳望远镜及周边设施表面与空气的温差。根据辐射涂层表面与空气的温度实测,对辐射涂层抑制太阳望远镜及周边设施发热进行了可行性研究,研究表明所选的辐射涂层具有一定的抑制物体表面与空气温差的能力,辐射涂层相对水冷具有控温效果好、适用范围广等优势,可用于地基太阳望远镜及周边设施表面的温度控制。

Other Abstract

The earth-based solar telescope and its surrounding facilities could be heated by the solar radiation during the operation, the air near the telescope optical path could be heated by the hot surfaces, thereby forming the atmosphere turbulence around them which causes the degradation of the image quality. The method of alleviating the influence from the atmosphere turbulence on the image quality is to suppress the temperature differences between the surface of the solar telescope, its surrounding facilities and the air. According to the actual measurement of the coating layer temperature and the air temperature, the feasibility analysis about the temperature control by the coating layer on the surface of the solar telescope and its surrounding facilities is presented in this paper. The result shows that the coating layeris capable of keeping its temperature close to the air temperature in the complicated thermal environment. Compared with the water cooling, the coating cooling is much better for the temperature control and more applicable. All these methods make the coating cooling feasible for the temperature control of solar telescope and its surrounding facilities.
