Expected Performance of Adaptive Optics in Large Aperture Solar Telescopes
Abstract
Solar adaptive optics has become an indispensable tool for high resolution solar observations. New generation solar telescopes, such as the 4 m aperture Advanced Technology Solar Telescope, introduce a new set of challenges to solar adaptive optics correction. Larger aperture sizes are more susceptible to the effects on AO correction performance of the extended field-of-view of the cross-correlating Shack-Hartmann wavefront sensor. Observations at large zenith angles further enhance these field-of-view effects and can introduce more performance reductions due to atmospheric dispersion. We study the expected correction performance of solar adaptive optics systems in large aperture solar telescopes using an end-to-end adaptive optics simulation package.
