Drone-based area scanning of vegetation fluorescence height profiles using a miniaturized hyperspectral lidar system

We have developed a compact hyperspectral lidar system based on a continuous-wave (CW) 445 nm diode laser and a double Scheimpflug imaging arrangement. The light-weight construction allows the integration of the system on a commercial drone. Airborne, range-resolved spatial imaging of vegetation fluorescence is demonstrated.
The authors gratefully acknowledge the continuing support from Professors Sailing He and Guofu Zhou. We are also very grateful to Ying Li, Ying Li, and Jinlei Wang for assistance in the measurements and Klas Rydhmer, Alfred Strand, and Mikael Ljungholm for contributions in the early work on hyperspectral Scheimpflug systems.
