深空探测拉曼光谱技术研究进展

Significance The detection of material composition on the surface of celestial bodies has always been an important content in lunar and deep space exploration.At present, the main detection means of material composition on the surface of celestial bodies is visible-near -infrared spectroscopy.Given the wide variety of material components on the surface of celestial bodies, attention should be paid to their chemical properties and content.The current single payload is difficult to meet these requirements, and it is necessary to develop new scientific payload technologies.Over the past two decades, 特邀综述 第 43 卷 第 8 期/2023 年 4 月/光学学报 consider the priorities of various scientific mission objectives.Fluorescence suppression is still one of the main problems faced by Raman spectroscopy.Infrared/ultraviolet excitation, time gating, frequency -shift excitation, and photobleaching are effective methods for suppressing fluorescence in deep -space Raman spectrometers.Raman spectroscopy technology for deep space exploration requires the support of many key components, and key components such as intensifiers and gratings still need to be developed. Conclusions and ProspectsRaman spectroscopy is a very powerful tool for detecting the composition of astronomical matters and is being applied by increasingly more deep space exploration missions.At present, the development trend of Raman spectroscopy technology for deep space exploration is modularization and miniaturization, multi -technology joint detection, long -range and short -range joint detection, and diversified detection fields.
