Abstract

A new technique is suggested for wavefront reconstruction from gradient measurements on the basis of solution of the variational problem. The spatial frequency transfer function is derived for its reconstructor. The reconstruction accuracy is studied at different spatial spectra of wavefront distortions in numerical simulation. The reconstructor sensitivity is analyzed in the case of data loss in some nodes of the measuring grid.
