AOTF成像光谱仪及其在青藏高原多尺度遥感中的试验应用

An AOTF hyperspectral imager:The multi-scale remote sensing of Tibetan Plateau

简要阐述了AOTF的光学滤波机理和AOTF成像光谱仪的系统架构,研制了一套基于AOTF的地面成像光谱试验系统,将其应用于青藏高原多尺度遥感试验,针对高原植被试验区获取了不同尺度的成像光谱数据,为多尺度遥感试验提供了更为丰富的地面支持及比对数据.通过对数据的处理分析,证明了该技术在工程上的可行性,并为遥感图像混合像元分解等问题提供了新的解决方案.

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