CASOAR - An infrared active wave front sensor for atmospheric turbulence analysis
Abstract
An heterodyne wavefront sensor CASOAR designed to analyze spatial and temporal fluctuations of atmospheric disturbed wavefronts along horizontal paths close to the ground is considered. The system was calibrated and tested on outdoor sites in different atmospheric conditions. CASOAR is capable of rapidly measuring the deformations of a wavefront with 1 deg accuracy. It is an active self-contained and self-aligned system based on its own light source (CW CO2 laser).
