Extended-Object Reconstruction Using Speckle Imaging Technique at SHAO

Speckle imaging technique is one of the several effective approaches, which can overcome atmosphere turbulence effects to improve resolution power of the ground-based telescope. It has been widely used in the astronomical observation research. The observation experiments using this technique have been made on 1.56-m telescope with an EMCCD speckle camera at SHAO. Results are presented from a series of experiments including binary stars and simulated satellite. A brief overview of the image reconstruction algorithm is presented. The results confirm that speckle imaging techniques can be used with an EMCCD imaging system to provide a powerful and flexible method for imaging objects of moderate magnitude.
