Wavefront correctors are the key components of the adaptive optical systems and the techniques to fabricate wavefront correctors have been developed for many years.This paper introduces several kinds of wavefrom correctors that are commonly used in adaptive optical systems,such as the deformable mirror with discrete actuators and continuous faceplate,segmented deformable mirror,membrane deformable mirror,bimorph deformable mirror,MEMS deformable mirror,liquid crystal corrector and the adaptive secondary mirror.The realization methods of the wavefront correctors and their working principles are presented in detail,and the performance,the number of degrees of freedom and the speed of response are compared.Finally,it summarizes the technology innovations and development trends of the wavefront correctors in the new applications.
