Paper Abstract

In layer-oriented adaptive optics, multiconjugation is performed in a much more efficient way than conventional wavefront sensing. This improved efficiency is impressive for high altitude layers and moderate for ground ones. On the other hand high altitude layers can be covered with only a limited field of view (where one can search for natural guide stars) while for ground layers the usable field of view is limited essentially by practical reasons. We introduce the further concept of multiple field of view layer oriented where a combination of sampling and covered field leads easily to sky coverages that nearly approach the whole sky with the usage of solely natural guide stars for 8m class telescopes.
