The resolution of astronomical imaging from large optical telescopes is usually limited by the blurring effects of refractive index fluctuations in the Earths atmosphere.In this paper,we develop a lucky imaging system to restore astronomical images through atmosphere turbulence on l.23 m telescope.Our system takes very short exposures,on the order of the atmospheric coherence time.The rapidly changing turbulence leads to a very variable point spread function (PSF),and the variability of the PSF leads to some frames having better quality than the rest.Only the best frames are selected,aligned and co added to give a final image with much improved angular resolution.Our system mainly consists of five parts: preprocessing,frame selection,image registration.image reconstruction,and image enhancement.()ur lucky imaging system has beensuccessfully applied to restore the astronomical images taken by a l.23 m telescope.We have got clear images of moon surface.Jupiter,and Saturn,and our system can be demonstrated to greatly improve the imaging resolution through atmosphericturbulence.
