摘要
首先介绍了欧空局(ESA)火星快车(Mars Express)上装载的火星大气特征研究光谱 仪(Spectroscopy for Investigation of Characteristics of the Atmosphere of Mars, SPICAM)和红外矿物光谱制图 仪(Observatory of Mineralogy, Water, Ice and Activity or IR Mineralogical Mapper, OMEGA)以及美国火星勘测轨道飞行器(Mars Reconnaissance Orbiter, MRO) 上搭载的紧凑型火星勘测成像光谱仪(Compact Reconnaissance Imaging Spectrometer for Mars, CRISM)的特点指标 及其相关应用。然后介绍了新型分光器件——声光可调谐滤波器(Acousto-Optic Tunable Filter, AOTF) 的原理及特点,并对拟用于月球探测的基于该分光技术的CE-3红外成像光谱仪和CE-5月球矿物光谱分 析仪进行了简要介绍。最后介绍了其光谱定标、辐射定标以及在宽温度范围内工作时的温度特性分析与校正,为AOTF在 深空探测中的进一步应用提供了技术参考。
Abstract
First, the specifications and related applications of the SPICAM and OMEGA onboard Mars Express of European Space Agency (ESA) and the CRISM onboard Mars Reconnaissance Orbiter (MRO) of U.S. are presented. Then, the principle and characteristics of a new device, the Acoustic-Optic Tunable Filter (AOTF), are presented in brief. Both the infrared imaging spectrometer and the lunar mineral spectrometer based on AOTFs which will be used for CE-3 and CE-5 missions respectively are described. Finally, the spectral calibration, radiometric calibration and temperature analysis and correction of both instruments in a wide temperature range are discussed. The experimental result will be used as the technical reference for the further applications of AOTFs in deep space exploration.
