月球表面原位光谱探测技术研究与应用（特约）

探测月球与行星表面物质化学成分是了解其起源及演化历史的关键,而光谱探测技术则是物质成分识别与定量反演研究的重要手段。原位（In-Situ）光谱探测有别于空间探测中的环绕器遥感及采样返回探测,是指在目标现场进行的近距离光谱探测。我国“嫦娥三号”任务科学研究与资源勘查,需要开展月球表面原位光谱探测技术研究,突破凝视型时序扫描的新型声光光谱探测关键技术,研发适应表面恶劣环境的高性能、轻小型、高可靠仪器,在国际上率先实现月球表面光谱原位探测及分析。论文结合以“嫦娥三号、四号”为典型应用的红外成像光谱仪,介绍据此发展起来的月球表面原位光谱探测技术,包括探测机制、工作模式及仪器的功能、性能与应用;最后,也简要介绍了即将应用的“嫦娥五号”月球矿物光谱分析仪。

Research and applications of In-Situ lunar surface spectral detection technology(Invited)

Exploring the chemical composition of materials on the surface of the moon and planets is the key to research its origin and evolution history. Spectral detection technology is the major methods of material composition recognition and quantitative inversion. In-Situ spectral detection is different from remote sensing and sampling return detection, it refers to the short distance spectral detection performed at the target site. The lunar science research and resource exploration of "Chang'e-3 "mission need to implement the first In-Situ spectral detection technology on the lunar surface, by breaking through the key technologies of the new acousto-optic spectroscopic detection of staring time series scanning, we have developed high-performance, light and small, highly reliable instruments, adapted to the harsh surface environment, and become the first in the world to realize In-Situ spectral detection and analysis on the lunar surface of the moon. The paper takes "Chang'e-3 and 4" as typical applications, and introduces the In-Situ spectral detection technology of the lunar surface, including detection mechanism, working mode and the function, performance and application of the instrument; Finally, the "Chang'e-5" lunar mineral spectrometer was introduced which will be applied soon.
