The reconstruction of a wave front of optical radiation which contains turbulent distortions is carried out on the basis of the Hartmann method by approximating the wave function with Zernike polynomials based on estimates of local inclinations and is analyzed for high-intensity turbulent distortions. Based on the results of statistical analysis of information on phase distortions of radiation using a Hartmannogram formed in the plane of the receiving device, methods have been identified that allow reducing the residual reconstruction error caused by the presence of “strong” turbulence along a radiation propagation path.
