Paper Abstract

The possibility of designing and running an AO system working in the visible for observations with a large diameter telescope is still under debate due to the large number of sub-pupils required to properly sample the incoming WaveFront. On the other hand, the situation is much more relaxed in the IR, where r0 is much larger, and several systems are forthcoming or already in operation. Morossi et al. proposed to support IR AO system with on-line multi-aperture selection devices. They showed that the image quality of a ground-based telescope in the visual could be improved by means of pupil segmentation and on-line multi- sub-aperture selection notwithstanding the large D/r0 ratio.
