Abstract

We propose the concept of the new SCIDAR-based method to determine the characteristics of the atmospheric turbulent layers including its heights and strength. In this paper we discuss the possibility of the estimating of the heights of the atmospheric turbulent layers from the vertical profiles (along line of sight) of dimensionless characteristics of turbulence. The method is based on the analysis of the scintillation in crossed optical beams (with temporal lag) on the spaced subapertures of single Shack-Hartmann sensor (with field of view of order 40 arc.sec.) conjugated with the aperture.
