Abstract

Abstract

The limitation of classical adaptive optics and the basic principle of multi-conjugate adaptive optics are briefly introduced. The conjugate heights of single-conjugate and dual-conjugate systems are numerically simulated, and the gains of isoplanatic angle are demonstrated combined level-propagation and upright-propagation. The simulated results indicate that when the propagation distance is 20 km, the conjugation height has notable effect on the gain of the isoplanatic angle. For a single-conjugate system, the gain of isoplanatic angle is good in level propagation, but bad in upright, and the range of enlargement is limited during 3.6 km. For a dual-conjugate system, the deformable mirror for the first conjugate height mostly corrects the atmospheric turbulence near the pupil plane, and
