High Resolution Astrophysical Observations Using Speckle Imaging

Abstract

The reconstruction of complex solar surface features to a factor of ten finer than could normally be studied under prevailing seeing conditions has been demonstrated Previously, successful examples of speckle image reconstruction were limited to uncomplicated objects showing very high contrast structure. The ability to retrieve complex and low contrast image detail is a result of recognizing the need for high quality sensors capable of recording subtle intensity modulations in the data frames.
