Scientific paper

In order to understand Solar Prominences, we need to observe them at sub-arcsecond resolution, with a sub-second cadence. Present image reconstruction techniques, such as Speckle Interferometry, are capable of delivering high resolution images, but at a slow cadence. We propose the design for a Solar Limb Adaptive Optics system that would allow images to be captured at sub-second cadence with sub-arcsecond resolution. The challenge, with Solar Limb AO, is the use of faint Hα prominence structure near the limb, to derive wavefront measurements at hight speed. Regular, on-disk Solar Adaptive Optics have sufficient photon flux available, for the subaperture based wavefront sensor. In contrast, a Shack Hartmann wave- front sensor, which uses faint Hα prominence structure as its reference, is photon starved. Full aperture sensor concepts, such as Phase Diversity, may have to be considered. It is hoped that such a system, if successful, would be implemented on the upcoming Advanced Technology Solar Telescope.
