摘      要：A second generation solar adaptive optics（AO） system is built and installed at the 1-m New Vacuum Solar Telescope（NVST） of the Fuxian Solar Observatory（FSO） in 2015. The AO high-order correction system consists of a 151-element deformable mirror（DM）, a correlating Shack-Hartmann（SH） wavefront sensor（WFS）with a 3500 Hz frame rate, and a real-time controller. The system saw first light on Mar. 16, 2015. The simultaneous high-resolution photosphere and chromosphere images with AO are obtained. The on-sky observational results show that the contrast and resolution of the images are apparently improved after the wavefront correction by AO.
