摘要	Adaptive optics is an essential technology for large ground-based telescopes to correct atmospheric disturbances. Presently the large-aperture adaptive deformable mirror uses piezoelectric actuator or voice coil actuator, however both of them have their own problems. Then Giant Magnetostrictive Material (GMM) actuator has great advantage as the actuator for large aperture adaptive mirror, which has large stroke, high bandwidth, high precision and doesn’t require high drive voltage. The research ‘s aim is to use the GMM actuator to drive the deformable mirror, and to build a large-aperture adaptive mirror calibration experiment platform to study this new material actuator in the adaptive mirror, at the same time adaptive deformable mirror’s control method would be studied. This research could be considered as a pre-research for GLAO system of Chinese large optical infrared telescope.
