空间中性原子成像应用及发展

AN OVERVIEW OF SPACE ENA IMAGING METHODOLOGY AND APPLICATION

摘要: 本文回顾并分析了空间中性原子成像的科学意义、观测原理及其应用、技术发展历程、发展趋势等。中性原子成像发展经历了三个不同阶段,其应用能力和认可度不断提升,直至为其发射专门卫星开展观测。空间科学研究对空间中性原子成像提出了宽能域、时空高分辨的需求,并刺激了超薄死层Si-PIN传感器应用和光学调制技术引入发展,为将来空间天气监测等业务化应用发展奠定理论和技术基础。

Abstract: Space ENA imaging can provide global or remote view of ions distribution and variation,which is the advantages compared to in situ measurement,and it has been more and more taken as an important space measurement method in missions. There were 3 phases of space ENA imaging developing. The methodologies and technologies of space ENA imaging were overviewed and analyzed,some requirements and trends of ENA measurements were proposed.
