Scientific paper

The paper describes the decade history and the recent advances in the field of the telescopes, where the nonlinear-optical effects are used for the correction for image distortions, caused by the defects and deformations of the primary mirror and of some other elements. Described are the schemes, based on phase conjugation use, which can work with the coherent radiation (beam direction, laser collimators and imaging with coherent illumination) and the schemes, based on the use of the dynamic holography, applicable to the remote objects (astronomy, Earth observation) in the incoherent radiation with the wide spectrum.
