Development of Lidar Techniques for Environmental Studies

Forskningsoutput: AvhandlingLicentiatavhandling

Abstract

The lidar group in Lund has performed many DIAL measurements with a
mobile lidar system that was first described in 1987. The lidar system is based on a Nd: YAG-pumped dye laser. During the last few years the lidar group has focused on fluorescence imaging and mercury measurements in the troposphere. In 1994 we performed two campaigns: one fluorescence imaging measurement campaign outside A vignon, France and one unique lidar campaign at a mercury mine in Almaden, Spain. Both campaigns are described in this thesis.
This thesis also describes how the mobile lidar system was updated with the graphical programming language LabVIEW to obtain a user friendly lidar system. The software controls the lidar system and analyses measured data. The measurement results are shown as maps of species concentration. All electronics and the major parts of the program are described. A new graphical technique to estimate wind speed from plumes is also discussed. First measurements have been performed with the new system.
