Abstract

High spatial resolution is of the utmost importance for understanding the phenomena that are present on the solar surface. Several techniques for wave-front sensing and image reconstruction have been proposed and used with varying degrees of success. The results of a wave-front sensing and image-reconstruction experiment that uses phase information obtained by comparing in-focus and out-of-focus images are presented. The data, a series of snapshots of solar granulation, were taken with the Vacuum Tower Telescope at the National Solar Observatory at Sacramento Peak. The experiment shows the potential utility of such a technique. Advantages and limitations are discussed.
