摘　　要：基于波像差分配理论,提出了某高分辨率空间相机的热控指标.在分析相机空间外热流环境的基础上,进行了热控方案设计,并利用热分析软件进行了高低温工况下的瞬态热分析.结合热平衡试验验证了热设计的有效性和正确性.Precise thermal control requirements of one high resolution space camera are introduced based on wave-front error allocation methods. Through the external environmental heat flux analysis, the detailed thermal control measures are put forward and transient thermal analysis for the extreme cases and thermal balance tests in the vacuum are carried out to validate the design. These results are useful for the precise thermal control of other space cameras.
