【摘要】 拉曼光谱仪以其可以无损伤的对矿物质以及有机物进行分析的特性已经被誉为探索火星矿物质的下一代工具。美国夏威夷大学研制的可移动拉曼雷达系统的探测距离已经达到了217m。本文分析了微型远程拉曼的研究现状及其在深空探测上的应用前景,并根据实验结果得出远程拉曼的测试距离与激光功率、曝光时间及被测物质的空间立体角基本成正比,推导了远程拉曼在深空探测中的可行性,并提出了远程拉曼光谱仪的设计构想,为远程拉曼的进一步研究提供可以借鉴的作用。更多还原

【Abstract】 Raman spectroscopy has been recognized as the next-generation instrument for the characterization of mineralogical and organic material without the need to perturb a sample during exploration of Mars.The mobile Raman lidar system has been developed for spectral measurements of samples located remotely at ranges of 217 meters by the university of Hawaii in America.This report analyses present study and application perspective during exploration of planet for Micro-Remote Raman.And at the base of experiment,it is reported that the measurement distance of Remote Raman is approximately direct proportion to laser power,exposal time,lens focus,and the spatial angle of the sample and deduced that Remote Raman for the spatial exploration is feasible.Beside some new design notion will be advanced about Remote Raman spectrometer and all these might give some helps for the further study.更多还原
