Paper Abstract

The application of large-aperture bimorph mirrors in an adaptive telescope is suggested and analyzed for the first time. Their advantages and peculiarities as compared with adaptive mirrors, having discrete control actuators, are discussed. The principles of a new generation adaptive telescope design and use of adaptive bimorph mirror in the capacity of the main telescope mirror for large-scale low-frequency wavefront distortion compensation are suggested on the basis of radiation distortion analysis in the telescope. The piezoceramic plates above 100 mm in diameter which were made according to two different production technologies are suggested for the first time for the building of large-dimension bimorph structures. The multilayer mosaic forming method of these structures is described. The computer simulation results of the 3.3-meter bimorph adaptive mirror design and low-order optical aberration compensation are presented.
