Abstract:

A method is proposed for determining the parameters of the spectrum of turbulent medium refractive index fluctuations. Experimental data for laser beams of different diameter and wavelengths are used for this purpose. The relation between the variance of the beam centroid displacements and the correlation function of intensity fluctuations in the observation plane is employed. The method consists in estimating the correlation function of intensity fluctuations and beam wandering in the observation plane and solving the set of equations written based on analytical relationship between the above parameters.
