Recently, laser-induced breakdown spectroscopy (LIBS) has been developed for the elemental analysis of geological samples for application to space exploration. There is also interest in using the technique for the analysis of water ice and ice/dust mixtures located at the Mars polar regions. The application is a compact instrument for a lander or rover to the Martian poles to interrogate stratified layers of ice and dusts that contain a record of past geologic history, believed to date back several million years. Here we present results of a study of the use of LIBS for the analysis of water ice and ice/dust mixtures in situ and at short stand-off distances (< 6.5 m) using experimental parameters appropriate for a compact instrument. Characteristics of LIBS spectra of water ice, ice/soil mixtures, element detection limits, and the ability to ablate through ice samples to monitor subsurface dust deposits are discussed.
最近，激光诱导击穿光谱法（LIBS）已被开发用于地质样品的元素分析，以应用于太空探索。人们也对使用该技术分析火星极地地区的水冰和冰/尘混合物感兴趣。该应用是一种用于着陆器或漫游车的紧凑型仪器，用于探测火星极地含有过去地质历史记录的冰层和尘埃分层，据信这些记录可追溯到数百万年前。在此，我们展示了一项研究的结果，该研究使用适合紧凑型仪器的实验参数，对水冰和冰/尘混合物进行原位和短距离（<6.5米）的LIBS分析。讨论了水冰、冰/土混合物的LIBS光谱特征、元素检测限以及通过冰样烧蚀以监测地下尘埃沉积物的能力。
