Abstract
Reconstruction of a wavefront containing turbulent distortions of optical radiation is considered. The Hartmann method based reconstruction is carried out using the wave function approximation by Zernicke polynomials according to estimates of local slopes and analyzed on the basis of filling hartmannograms with focal spots, depending on the telescope circuitry. The volume and quality of information about phase distortions of radiation are estimated using the hartmanograms formed in the plane of the receiver, thereby developing methods for reducing the the telescope induced residual reconstruction error.
