An AOTF hyperspectral imager: The multi-scale remote sensing of Tibetan Plateau
AOTF成像光谱仪及其在青藏高原多尺度遥感中的试验应用

The optical filtering principles of AOTF and system architecture of AOTF hyperspectral imager have been presented. An experimental field hyperspectral imaging system has been setup and been applied in the multi-scale remote sensing experiment in the Tibetan Plateau. Hyperspectral images of different scale have been collected in the experiment area for plateau vegetation, and more abundant field supporting and comparative data have been provided. By data processing, the engineering feasibility of the technique has been validated, and a novel method has been introduced for mixed pixel unmixing in remote sensing images.
