New method for wavefront reconstruction from measured gradients is proposed on the basis of the solution of variational problem. Spatial frequency transfer function is obtained for its reconstructor. Accuracy of the restoration is studied, by methods of numerical modeling, at different spatial spectra of wavefront distortions. Reconstructor sensitivity is analyzed in the case of data loss in some nodes of measuring grid.
