火星科学实验室漫游车“好奇号”降落在盖尔陨石坑中 5 公里高的层状物质堆底部附近。 ChemCam 仪器安装在流动站桅杆上，旨在使用与远程微成像仪 (RMI) 耦合的激光诱导击穿光谱仪 (LIBS) 远程确定距离流动站几米的土壤和岩石的成分。我们概述了 ChemCam 的 RMI 在火星运行第一年期间进行的各种成像研究。从 Sol 10 到 Sol 360 采集了 1182 个单独的全色 RMI 图像，以记录 ChemCam LIBS 测量结果并表征土壤、岩石和流动站硬件。我们展示了几种类型的衍生成像产品，包括激光拍摄前后拍摄的图像马赛克、增强最细微激光凹坑的差异图像、与彩色 Mastcam-100 图像的合并、使用 Z 堆栈技术的微地形以及延时电影。 RMI 的极高空间分辨率能够解析亚毫米尺度的岩石纹理，从而提供有关岩石起源（火成岩与沉积岩）的线索，并揭示有关其成岩和风化演化的信息。除了在 LIBS 可达范围（1-7 m）内具有科学价值外，我们还表明，RMI 还可以作为强大的长距离侦察工具来表征距离流动站数公里范围内的景观。
The Mars Science Laboratory rover, “Curiosity” landed near the base of a 5 km-high mound of layered material in Gale crater. Mounted on the rover mast, the ChemCam instrument is designed to remotely determine the composition of soils and rocks located a few meters from the rover, using a Laser-Induced Breakdown Spectrometer (LIBS) coupled to a Remote Micro-Imager (RMI). We provide an overview of the diverse imaging investigations that were carried out by ChemCam’s RMI during the first year of operation on Mars. 1182 individual panchromatic RMI images were acquired from Sol 10 to Sol 360 to document the ChemCam LIBS measurements and to characterize soils, rocks and rover hardware. We show several types of derived imaging products, including mosaics of images taken before and after laser shots, difference images to enhance the most subtle laser pits, merges with color Mastcam-100 images, micro-topography using the Z-stack technique, and time lapse movies. The very high spatial resolution of RMI is able to resolve rock textures at sub-mm scales, which provides clues regarding the origin (igneous versus sedimentary) of rocks, and to reveal information about their diagenetic and weathering evolution. In addition to its scientific value over the range accessible by LIBS (1–7 m), we also show that RMI can also serve as a powerful long distance reconnaissance tool to characterize the landscape at distances up to several kilometers from the rover.
