Other Abstract

Lucky imaging is a relatively simple post image processing technique, which uses an image-quality evaluation function to evaluate quality of short exposure images and then a  few of high quality images are selected, shifted and alassical algorithm of lucky imaging technology. a lucky imaging solution for the 2.4m telescope is presented, and a local GPU acceleration algorithm is proposed. A high-resolutionj image of binary star with an angrlar separation of 0.3″ is obtained. The GPU acceleration algorithm is designed to conduct parallel computing during the image selecting period. The feasibility of the acceleration algorithm for lucky imaging and its calculation bottleneck are discussed. The experimental results show that the images taken by 2m large aperture telescope under the near infrared condition can be used to rebuild a high-resolution image (FWHM 0.2″) by lucky imaging technology. A GPU device can accelerate the lucky imaging algorithm, and improve the efficiency of the whole algorithm.
