We present the design of a full waveform hyperspectral light detection and ranging (LiDAR) and the first demonstrations of its applications in remote sensing. The novel instrument produces a 3D point cloud with spectral backscattered reflectance data. This concept has a significant impact on remote sensing and other fields where target 3D detection and identification is crucial, such as civil engineering, cultural heritage, material processing, or geomorphological studies. As both the geometry and spectral information on the target are available from a single measurement, this technology will extend the scope of imaging spectroscopy into spectral 3D sensing. To demonstrate the potential of the instrument in the remote sensing of vegetation, 3D point clouds with backscattered reflectance and spectral indices are presented for a specimen of Norway spruce.
我们展示了一种全波形高光谱光探测与测距（LiDAR）的设计，并首次展示了其在遥感中的应用。这种新型仪器可生成带有光谱后向散射反射率数据的三维点云。这一概念对遥感以及其他目标三维检测和识别至关重要的领域产生了重大影响，如土木工程、文化遗产、材料加工或地貌学研究。由于目标的几何形状和光谱信息可从单次测量中获取，这项技术将把成像光谱学的范围扩展到光谱三维传感。为了证明该仪器在植被遥感中的潜力，给出了挪威云杉样本的带有后向散射反射率和光谱指数的三维点云。
