Experimental tests and radiometric calculations for the feasibility of fluorescence LIDAR-based discrimination of oil spills from UAV

Abstract This paper presents experimental tests and radiometric calculations for the feasibility of an ultra-compact fluorescence {LIDAR} from an Unmanned Air Vehicle (UAV) for the characterisation of oil spills in natural waters. The first step of this study was to define the experimental conditions for a {LIDAR} and its budget constraints on the basis of the specifications of small {UAVs} already available on the market. The second step consisted of a set of fluorescence {LIDAR} measurements on oil spills in the laboratory in order to propose a simplified discrimination method and to calculate the oil fluorescence conversion efficiency. Lastly, the main technical specifications of the payload were defined and radiometric calculations carried out to evaluate the performances of both the payload and the proposed discrimination method.
