Image Restoration Problems for New-Generation Telescopes
The resolution of ground-based telescopes will be improved by means of Adaptive Optics (AO), a new technology which can compensate for the effects of atmospheric turbulence. As a consequence several large and innovative telescopes are in an advanced phase of design or construction. A very interesting example is provided by the Large Binocular Telescope (LBT) which will be available in a few years. In this paper we discuss a few restoration problems related to the processing of the images of LBT.
