    摘要:

    首先介绍了热红外高光谱成像应用的独特优势,然后论述了机载热红外高光谱成像仪(Airborne Thermal-Infrared Hyperspectral Imaging System, ATHIS)灵敏度优化的设计方法,结合仪器特点介绍了实验室矿物发射光谱和气体吸收光谱测量的辐射模型,分析了样本红外光谱与温度分离的数据处理流程。在此基础上,利用ATHIS开展了矿物发射光谱和气体红外吸收光谱的实验室测量,结果表明,利用ATHIS仪器和本文建立的数据方法已具备准确反演矿物发射率光谱和气体吸收光谱的能力,后续将利用该仪器开展多平台的遥感应用试验,为未来开展星载热红外高光谱相机研制和数据处理方法奠定基础。

    Abstract:

    In this paper, we introduced the unique advantages of the thermal infrared hyperspectral imaging in many applications, and then discuss the design to optimize sensitivity of the airborne thermal-infrared hyperspectral imaging system (ATHIS). Additionally, we establish emission spectrum of laboratory minerals and build the radiation model to measure the absorption spectrum of gas, with which the procession of separation of spectrum and temperature is analyzed. Finally, ATHIS is used to carry out laboratory measurements of mineral emission spectrum and gas infrared absorption spectrum. The results show that the data method we proposed for ATHIS can accurately invert mineral emissivity spectrum and gas absorption spectrum. In the future, ATHIS will be used to carry out multi-platform remote sensing application experiments, which will lay the foundation for future development of space-borne thermal infrared hyperspectral camera and data processing methods.
