Bimorph adaptive mirror

A cooled copper adaptive mirror based on a double bimorph structure is proposed for the compensation of large-scale optical aberrations, including those that occur in power systems with an output up to 15 kW. The construction of the adaptive mirror is described and the results are given of calculations and of experimental studies of thermal deformations of the reflecting surface, of the response functions of the control electrodes, and of the frequency properties of the mirror. Estimates are obtained of the effectiveness of compensation of low-order optical aberrations.
