Abstract
The paper describes the multi-conjugate adaptive optics systems and identifies the features of optical conjugations of adaptive mirrors with turbulent layers for ground-based solar telescopes. The optimal size of the field of view for a solar telescope operating under average atmospheric conditions has been calculated. The size of the optimal field of view is equal 10 arc. sec. Recommendations are given for the development of MCAO systems for ground-based solar telescopes. The concept of a system for determination of 3D wavefront distortions for the Large Solar Telescope LST-3, as well as for the wavefront registration in the Large Solar Vacuum Telescope, is proposed.
