Data Pre-procesing in Astronomical Speckle Imaging

More Information
  • Received Date: March 04, 1997
  • Revised Date: April 03, 1997
  • Published Date: October 14, 1997
  • 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.
