In this paper
we develop a lucky imaging system to restore astronomical images through atmosphere turbulence. 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. Our lucky imaging system has been successfully applied to restore the astronomical images taken by a 1.23m telescope. We have got clear images of moon surface and Jupiter
and our system can be demonstrated to greatly improve the imaging resolution through atmospheric turbulence. 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).
