Estimating optical turbulence strength using measurements of wavefront distortions

The paper describes the results of measuring the structural parameters of optical turbulence for different altitudes in the atmosphere above the Large Solar Vacuum Telescope of the Baikal Astrophysical Observatory. The structural parameters of optical turbulence we estimated from the measurement data of the Shack-Hartmann sensor for individual atmospheric layers by applying the analysis of wavefront distortions in crossed optical beams. To estimate the structural parameters of optical turbulence, we propose an approach based on statistical averaging normalized dimensionless characteristics of turbulence, the Fried parameter and averaged profile of optical turbulence at a given site.
