摘　　要：空间望远镜光学组件的温度稳定性对其分辨率的提高起到至关重要的作用,温度变化过大会使光学部件之间的相对位置发生变化,导致光学主轴倾斜,改变光学部件的面形。根据激光测距望远镜热控设计的特点和难点,基于光机热一体化的设计理念,以“被动热控为主,主动热控为辅”思想为指导,实现了望远镜光学组件的精密控温;参与了整星热平衡试验,验证了单机热设计的准确性和可靠性。The temperature stability plays a significant role for the revolution of space telescope optical component.The exceed temperature difference between the optical component and the installation structure changes the relative location which tilt the optical axis and change the optical component surface shape.According to the features and the difficulties of laser ranging telescope thermal design,basing on the ideas of optical-structure-thermal integrated design and'the passive thermal control primary,the active thermal control secondary',I accomplish the precision thermal control of telescope optical component.More importantly,the laser ranging telescope within the satellite finished the thermal balance test and verify the correctness and reliability of the thermal design.
