Paper Abstract

The resolution limit attainable by large ground-based telescopes is limited by the refraction index fluctuations of the turbulent atmosphere. To overcome this limitation Adaptive Optics systems measure and compensate atmospheric-induced distortions. When working in the visible, only a partial compensation is possible. We analyze the image formation process in these conditions. We provide a model for the wave front statistics, which allows a simple estimate of the instantaneous PSF. New deconvolution techniques could be developed by using this approximation.
