Compared with hyperspectral remote sensing in visible-light, near infrared and short-wave infrared spectra, hyperspectral remote sensing in the thermal infrared spectrum has unique advantages, especially in the fields of mineral identification and pollution gas. At present, infrared hyperspectral imagers are rare and mainly airborne. In this article, the basic principle and design features of a newly developed airborne thermal-infrared hyperspectral imaging system (ATHIS) are detailed, and separate validation experiments of laboratory and aerial remote sensing experiments are carried out. Measurements and comparative analysis of infrared emissivity spectra of the typical minerals were performed in the laboratory. In the summer of 2019, the instrument carried out flight tests in Hengdian Town, Dongyang City, Zhejiang Province, China. The results show that ATHIS can also accurately acquire the target emissivity spectrum. In the future, the instrument will also be used to carry out key technology verification and data-processing application research of space infrared hyperspectral imagers plan.

新型机载热红外高光谱成像仪系统:初步验证

与可见光、近红外和短波红外光谱的高光谱遥感相比,热红外光谱的高光谱遥感具有独特的优势,特别是在矿物识别和污染气体领域。目前,红外高光谱成像仪很少见,主要是机载。本文详细介绍了一种新研制的机载热红外高光谱成像系统(ATHIS)的基本原理和设计特点,并分别进行了实验室和航空遥感实验的验证实验。在实验室对典型矿物的红外发射光谱进行了测量和对比分析。2019年夏,该仪器在浙江省东阳市横店镇进行飞行试验。结果表明,ATHIS也能准确获取目标发射率谱。未来,该仪器还将用于开展空间红外高光谱成像仪计划的关键技术验证和数据处理应用研究。
