Paper Abstract

With the advent of high resolution imaging through the atmosphere, turbulence distribution measurement has become a key issue. The possibility to measure C2n profile from Shack-Hartman data, slopes and intensities, acquired on a unique point source has recently been demonstrated numerically.1 This method, called SCOSLIDAR, is exploited here on experimental data. From slopes and intensities of a mid-infrared wavefront sensor, C2n profiles along an oblique line of sight are estimated and compared to local measurements. Time averaged profiles are confronted to a profile deduced from similitude law.
