Abstract
During 1994 an experiment took place over the North Sea in order to derive the infrared atmospheric scintillation and beam deformation process. An infrared point source was positioned at a platform in sea, with a height ranging between 1.5 and 7 m above the sea level. Some additional sources, at different height levels, were installed later on in the experiment. The receiver system was placed at 18 km on a pier near the coast of the Netherlands. Recordings took place with the receiver at two heights, 40 and 15 m above the average sea level. A single recording consisted of 10 seconds of measurements at 25 Hz with a 64 X 64 elements Cincinnati IRC-64A camera in the 3 - 5 micrometers band. Examples of these recordings are presented. The data were analyzed for scintillation effects, atmospheric point spread function effects and refraction effects. These data are compared to the atmospheric conditions that were recorded simultaneously, in order to model the infrared scintillation effects with meteorological conditions. Results of these comparisons are shown.
