欧空局ExoMars探测器使命的数据将为进一步研究天文学/外星生物学提供宝贵的投入。紧凑型拉曼激光诱导击穿光谱（LIBS）仪器的主要目标是寻找矿物产品作为火星表面和地下样本中当前和/或过去生物发生活动的指标。拉曼光谱和LIBS的固有特性使这一组合仪器成为寻找生物标志物的独特和非常强大的工具，因此被视为使命中矿物分析的最高优先级仪器。我们开发了一个软件包，用于仪器数据输出的机载处理，包括矿物相和生物标志物的光谱调节和搜索匹配表征。在本文中，我们展示了软件包的数学和物理基础。
Data from the ESA ExoMars Rover Mission will provide invaluable input for further studies in astro/exobiology. The search for mineral products as indicators of present and/or past biogenetic activities in Mars' surface and subsurface samples is the main objective of the compact Raman-laser-induced breakdown spectroscopy (LIBS) instrument. The inherent features of Raman spectroscopy and LIBS make the combined instrument a unique and very powerful tool in the search for biomarkers and hence it is regarded as the highest priority instrument for mineral analysis within the mission. We have developed a software package for the on-board processing of the instrument's data outputs, including spectral conditioning and search-match characterization of mineral phases and biomarkers. In this paper we show the mathematical and physical basis of the software package.
