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.
