英文摘要	In this paper an active optics experiment platform based on a 1.2 m thin primary mirror is designed and established. Several experiments are conducted on the platform: the influence functions of the active axial supports are measured, and the active optics system’s capability of fitting Zernike aberrations and correcting the mirror’s gravitational deformations are tested. The results show that the system’s fitting errors for the first 10 Zernike modes are less than 30%, and it is capable of reducing the RMS of the mirror’s gravitational deformation from 1.7λ to less than 0.18λ (λ = 650 nm) by active correction. Finally, the influence of the Zernike modes used in the active correction are studied. The results show that, as the number of Zernike modes used in the active correction increases, the residual RMS of the 1.2 m mirror’s gravitational deformation decreases and becomes steady when the number rises to over 14. © 2019 Optical Society of America
