In this paper,a deformable mirror is employed as a pupil filter in a super-resolution imaging system because it can be used to modulate optical field phase quickly and flexibly.The genetic algorithm is adopted to design pupil phase structures with different super-resolution parameters,and the closed-loop phase fitting of pupil filter is realized by modifying the closed-loop reference matrix of the adaptive optics system.On this basis,the experiments are conducted to compare the super-resolution imaging resu...
