Abstract

Estimates of atmospheric turbulence parameters can be calculated on the basis of data, obtained with wave front sensor. The method described is based on decomposition of phase fluctuations into Zernike series and analysis of statistics of this decomposition coefficients. Estimates of turbulence outer scale L0 and refractive index structure constant C2/n obtained in experiments with turbulence in water cell showed good agreement with previous results.
