Abstract

The airborne Wind Lidar system ALADIN Airborne Demonstrator (A2D) was developed in 2005 to validate the spaceborne ALADIN Lidar. It was successfully operated to measure 2D Wind pro�les onboard the DLR Falcon aircraft, during the last years. The launch of ALADIN within the Aeolus Project of the European Space Agency (ESA) is in 2014. In the same year, it is planed to �y A2D on board the research aircraft HALO with a newly developed scanning device. In the framework of this master thesis, scanner concepts for A2D on HALO were derived, that allow to measure 3D wind pro�les. Di�erent technologies are reviewed and validated to �nd the best de�ection principal for the system. This includes the design layout and optical veri�cation of Volume Phase Gratings, mirror systems and wedge prisms, with optical and mechanical speci�cation constraints from both, the Lidar system and the airborne platform. Out of three possible scanner con�gurations, that were characterised in the laboratory for their relevant optical properties, two were selected for more detailed integration into the opto-mechanical framework of the airborne Lidar system using 3D CAD models.
