Paper Abstract

To satisfy aberration correction in orbit for the large aperture and long focal length space telescope, propose a technical scheme for the use of the exit pupil deformable mirror. Firstly analyze the error sources on orbit and the necessity of active correction. Use Zernike polynomial to fit the wavefront aberration and set up deformable mirror influence function model of Gauss, then provide the deformable mirror control matrix and the control voltage calculation method. The simulation results show that the deformable mirror correction technique can effectively reduce the wavefront aberration of large aperture space camera in orbit. To verify the validity of the algorithms we used in the simulation, the experimental is setup and measurement results are achieved based on the laboratory adaptive optical system.
