Abstract

In the frame of phase I of the EUREKA project LASFLEUR (EU380) the biological, physiological, physical and technical aspects for the development of an European airborne fluorescence lidar for vegetation monitoring are evaluated. In order to find parameters suitable for remote sensing the investigation and comparison of far and near field fluorescence signatures are objects of this phase of the project. Starting from this point a sensor capable of taking laser induced fluorescence signatures from single plants, canopies and trees in the laboratory has been developed. An overview of the system is given in figure 1 and the following table.
