Other AbstractIn Hartmann-Shack wavefront sensing method, in order to have control signals for actuators of deformable mirror from the measured data of image displacement, procedure of wavefront reconstruction and decoupling of actuators are needed. In this paper the wavefront gradients sensing、wavefront reconstruction algorithms and decoupling of control signals are discussed. The limitation inherent in different wavefront reconstruction methods are analysed. The algorithm of controlling wavefront gradients of subapertures directly is also discussed. In this method several steps of wavefront reconstruction and decoupling are replaced by a single step. An experimental setup with a 19-element deformable mirror, a subaperture dividing optics, a comparing optical path and a IBM-PC computer has been established. The results of computer simulation and optical experiments are presented, it shows that a 19-element adaptive optics system can correct static and vary slow dynamic wavefront error, it can be used in large laser engineering system for wavefront error compensation and far field sharpness improvement.
