太阳极紫外和X射线成像观测是空间天气研究的重要内容,空间太阳极紫外(EUV)成像望远镜是为空间天气研究和预报研制的仪器。介绍了国内外太阳极紫外和X射线成像的发展状况,在此基础上引入19.5nm成像观测的科学目标。阐述了望远镜光学系统和成像相机传感器的设计。前者包括光学结构和基本参数、光学窗口的选择、多层膜设计、光学系统仿真结果;后者包括两种不同成像传感器的对比和选择、控制系统的设计。
Observations of solar animations and X-ray images are an important part of space weather research. Space-based extreme ultraviolet (EUV) imaging telescopes are instruments developed for the study and prediction of space weather. The development of solar UVA and X-ray imaging at home and abroad are introduced. Based on this, the scientific target of 19.5nm imaging observation is introduced. The design of telescope optical system and imaging camera sensor are described. The former includes the optical structure and basic parameters, the choice of optical window, multi-layer film design, optical system simulation results; the latter includes the comparison and selection of two different imaging sensors, control system design.
