Abstract :
In this paper the multiframe blind deconvolution method [Schulz, 1993] for the identification and correction of turbulence-induced phase aberrations in a ground-based telescope is extended to include the gains, backgrounds, and biases inherent in many charge-coupled device (CCD) cameras. In addition, an application of this method to real telescope data is described
