SuperCam is a highly integrated remote-sensing instrumental suite for NASA’s Mars 2020 mission. It consists of a co-aligned combination of Laser-Induced Breakdown Spectroscopy (LIBS), Time-Resolved Raman and Luminescence (TRR/L), Visible and Infrared Spectroscopy (VISIR), together with sound recording (MIC) and high-magnification imaging techniques (RMI). They provide information on the mineralogy, geochemistry and mineral context around the Perseverance Rover. The calibration of this complex suite is a major challenge. Not only does each technique require its own standards or references, their combination also introduces new requirements to obtain optimal scientific output. Elemental composition, molecular vibrational features, fluorescence, morphology and texture provide a full picture of the sample with spectral information that needs to be co-aligned, correlated, and individually calibrated. The resulting hardware includes different kinds of targets, each one covering different needs of the instrument. Standards for imaging calibration, geological samples for mineral identification and chemometric calculations or spectral references to calibrate and evaluate the health of the instrument, are all included in the SuperCam Calibration Target (SCCT). The system also includes a specifically designed assembly in which the samples are mounted. This hardware allows the targets to survive the harsh environmental conditions of the launch, cruise, landing and operation on Mars during the whole mission. Here we summarize the design, development, integration, verification and functional testing of the SCCT. This work includes some key results obtained to verify the scientific outcome of the SuperCam system.

SuperCam 校准目标：设计和开发

SuperCam 是一个高度集成的遥感仪器套件，用于 NASA 的火星 2020 任务。它由激光诱导击穿光谱 (LIBS)、时间分辨拉曼和发光 (TRR/L)、可见光和红外光谱 (VISIR) 以及录音 (MIC) 和高倍率成像的共同对准组合组成技术（RMI）。它们提供有关毅力漫游者周围矿物学、地球化学和矿物背景的信息。这个复杂套件的校准是一项重大挑战。每种技术不仅需要自己的标准或参考文献，而且它们的组合还引入了获得最佳科学输出的新要求。元素组成、分子振动特征、荧光、形态和纹理提供样品的完整图片，以及需要共同对准、关联和单独校准的光谱信息。由此产生的硬件包括不同种类的目标，每一种都涵盖了仪器的不同需求。SuperCam 校准目标 (SCCT) 中包含用于成像校准的标准、用于矿物识别和化学计量计算的地质样本或用于校准和评估仪器健康状况的光谱参考。该系统还包括一个专门设计的组件，样品安装在该组件中。该硬件使目标能够在整个任务期间在火星上发射、巡航、着陆和操作的恶劣环境条件下生存。这里我们总结了设计、开发、集成、SCCT 的验证和功能测试。这项工作包括为验证 SuperCam 系统的科学成果而获得的一些关键结果。
