The Research On The Astronomy Imaging Technology Of Diffraction-Limit Based On Lucky Imaging

With the effects of the atmospheric turbulence and the faster steps of the deep-space exploration, obtaining diffraction limited images of astronomical optical telescope becomes more and more fashionable. Lucy imaging technology appeared under this background. Lucy imaging technology finally gains a image that is clearer, more comfortable for vision, passing through the following steps—image acquisition, image quality evaluation, frame selection, image match and adding, image enhancement. This technique has a few advantages:not only effectively reducing the noise and image penumbra arosed by the atmosphere, but also improve the image resolution of ground-based telescope. This thesis introduces a series of problems. Firstly, some basic theory related to the Lucy imaging. Secondly, the data processing flow chart of Lucy imaging. Third, key problems and the corresponding resolution are showed. At last, explain the whole process of binary stars observing, and the significative analysis. Lucy imaging technology has laid a basis for further extending objects in the field of deep-space and other fields.
