Wavefront control with high-spatial cartridge-type piezostack deformable mirror

Abstract

To increase the cost-effectiveness of the piezostack deformable mirror we proposed to use the modular design of such wavefront correctors. Each module contains 5 individual multilayer actuators with size of 4*4 mm. The performance of 50*50 mm cartridge-type piezostack deformable mirror with 100 control elements was investigated. Main parameters of the developed wavefront corrector were estimated such as the local stroke, influence functions, the control bandwidth.
