Abstract

Two kinds of noises in speckle data aroused by the speckle image detecting system of Yunnan Observatory:recoding noise for specklegrame and systematic error coused by the difference of atmospheric seeing are discussed. Pre-processing methods to remove these noises are described. The results of experiments clearly show that the preprocessing is effective and it is necessary to achieve high resolution image reconstruction for astronomical objects.
