is paper demonstrates the efficiency of using a large bimorph adaptive mirror for correction of the large-scale low-frequency distortions of the wavefront. The correction of the low-order optical aberrations by this mirror is computer simulated. Theoretical approach to the problem of adaptive correction of distortions is described. The comparative analysis of the efficiency of bimorph mirror and adaptive mirror with discrete electromechanical actuators has been carried out. The simple and effective way of forming the mosaic bimorph structure using the multilayer piezoelectric elements is proposed.
