摘要

AIMS太阳望远镜的主镜在观测太阳时被加热，导致主镜温度升高。主镜与周围空气之间的温差会产生视象效应(镜面视象)，是影响望远镜成像质量的关键因素之一。本文利用CFD软件对不同环境风速、不同主镜观测角度和观测时间条件下的主镜及其周围空气温度场进行了数值模拟。根据温度场的计算，分析了不同条件下的视镜，评价了主镜热控制的必要性。镜视性的评价对主镜的热控制设计具有重要的指导意义。

Evaluation on mirror seeing for AIMS solar telescope

The primary mirror of AIMS solar telescope is heated during the observation of the sun, leading to temperature rise of the primary mirror. The temperature difference between the primary mirror and the surrounding air may cause the seeing effect (mirror seeing), which is one of the key factors influencing the image qualities of the telescope. In this paper, the temperature fields of the primary mirror and its surrounding air are simulated by the CFD software on the conditions of different ambient wind speeds, different observational angels of the primary mirror, and the duration of observation. According to the calculation of temperature fields, the mirror seeing on different conditions are analyzed and the necessity of thermal control of the primary mirror is evaluated. The evaluation of the mirror seeing is very helpful for the design of thermal control of the primary mirror.
