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。
Space ENA imaging can provide global or remote view of ions distribution and variation,which is the advanta-ges 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.
