Numerical Analysis of Wavefront Reconstruction under Conditions of High-Intensity Atmospheric Turbulence

Abstract

The optical radiation wavefront distorted by turbulence is reconstructed based on the Hartmann method by approximating the wave function by Zernike polynomials according to estimates of local tilts. The reconstruction is analyzed for high-intensity turbulent distortions. Relying on results of statistical analysis of information on phase distortions of radiation by a hartmannogram formed in the plane of the receiving device, a method is suggested which allows one to reduce the residual reconstruction error caused by the presence of high-intensity phase fluctuations in the wavefront distribution.
