摘要
星载大气痕量气体差分吸收光谱仪具备对地观测、太阳光光谱定标、卤素灯探测器自检三种工作模式,所以需要三条相应的光学系统光路。为了使得光路得到充分利用,三条光学系统光路共用一部分光路,故设计太阳挡板活动部件、光路切换活动部件和漫射板定标活动部件用于切换三条光路。三个活动部件进行了部件寿命试验,而且整机进行了热真空和热平衡试验,实验结果表明活动部件运行正常,活动部件满足寿命要求和环境适应要求.
Spaceborne differential optical absorption spectrometer has three working modes: earth observation,spectrum calibration with solar, and halogen light detector self-inspection with halogen light. Therefore, three corresponding optical systems are needed. To make full use of the optical path, the three optical systems share part of the optical path. So, the solar baffle moving parts, the optical road switching moving parts, and the diffuser plate calibration moving parts are designed to switch the three optical paths. The three moving parts were tested for life, and the whole machine was tested by thermal vacuum and heat balance. The experimental results show that the moving parts are operating normally, and the moving parts meet the life requirements and environmental adaptation requirements.
