Design and Aerial Experiment of Offner Imaging Spectrometer

介绍一种Offner结构高分辨率推扫式成像光谱仪的设计,包括光学结构设计、数据获取与存储系统配置、基于数据库的光谱图像拼接软件设计以及成像光谱仪波长标定和辐射标定方法.其次介绍成像光谱仪在青藏高原陆面敏感因子航空遥感实验中的使用情况,包括实验概况、成像光谱仪及其采集系统在机舱内的安装调试、光谱仪的航拍参数以及航带光谱图像的拼接处理,最终获取到高分辨率的高光谱图像立方体.仪器的首次航拍飞行实验取得预期成果.

This paper describe the design of a high-resolution pushbroom imaging spectrometer, including the optical system, data ac- quisition and storage system, spectral image stitching software based on database, the wavelength calibration and the radiation calibra- tion. Then describe an airborne remote sensing experiment that the imaging spectrometer participate of land surface-sensitive factor at Qinghal-Tibetan Plateau, including experimental overview, the installation of imaging spectrometer and its acquisition system, the ac- quisition parameter and lane spectral image stitching algorithm. Finally we get the high-resolution hyperspectral image cube, the first aerial experiment of the imaging spectrometer achieve the expected results.
