Abstract
Fielding TNO’s LPT (Laser Propagation Testbed) for the first time in an international trial, a 3.6 km optical propagation path was created in a maritime environment between the city of Den Helder and the island of Texel in the Netherlands. Using a 1 W, 1556 nm laser beam, atmospheric propagation was investigated by capturing the resulting beam profile on a capture plate, which was imaged with a high-speed SWIR camera. Meteorological conditions were monitored using standard meteo stations, two visibility meters, two scintillometers and aerosol equipment. Over two weeks of measurements, propagation conditions varied from windy with clear, blue skies to significantly limited visibility. In this paper, the setup is introduced and a first discussion of the relation between beam behaviour and meteorological conditions is presented.
