Abstract

Abstract

The serious effects of turbulence of the Earth atmosphere can be overcome so that the diffraction-limited resolution imaging of a large ground-basedast ronomical telescope can be achieved by the speckle imaging techniques. The original data required in these techniques are a series of the short-exposure speckle images reco rded with a speckle image detection system attached to the telescope. In comparison with the requirements for the original data, structure and properties of the new speckle image detection-system built at Yunnan Observatory are introduced. Some practical observation results got with this system showed that the requirements can be basically satisfied.
