A method for estimating the parameters of turbulence that was originally developed for collimated laser beams is applied to the case of a divergent beam. The estimate is based on an analysis of the correlation functions of the Zernike expansion coefficients of the phase. The results suggest that the method can be used for the estimation of the inner scale of turbulence in an experiment with a divergent laser beam. In the case of isotropic turbulence, it is also possible to estimate the outer scale of turbulence from the correlation functions of lower-order modes.
