摘要
月球紫外-可见-近红外反射光谱(强度,反照率以及吸收特征)是研究月球表面物质组成的重要手段。文章简要介绍了月球表面反射光谱的基本特征、形成机制以及现有月球反射光谱数据及其解析方法。这些方法主要有光谱参数、连续背景扣除、高斯反卷积分析以及主成分分析。还讨论了高光谱探测器在月球探测中的应用前景、已有方案以及获取新的月球样品对月球反射光谱研究的重要性。
The UV-VIS-NIR reflectance spectra of the Moon are an important tool to interpret Moon surface composition. This paper summarizes the basic concepts of reflectance spectroscopy of the surface of an airless body. The mechanisms by which minerals absorb light are reviewed. The major techniques for the analysis of lunar spectral data are introduced. These include continuum removal, Gaussian deconvolution, principal component analysis, and spectral parameters for compositional mapping. Finally, the importance of high spectral resolution mapping for future lunar research is described.
