Paper Abstract

Modeling the performance of future ground-based extremely large telescopes with the AO system requires an atmospheric model and a corrective algorithm. The atmospheric model employed here is the ORM 7 layer model with an outer scale distribution. Using an analytical algorithm for atmospheric correction the performance of the Euro50 telescope is analyzed. The influence of a distributed outer scale on the strokes of the adaptive mirrors is investigated. It is concluded that for modeling the AO system performance the account for variations of outer scale with altitude is of not great importance, and a simplified atmospheric model with the effective outer scale common for all layers may be used. The knowledge of effective outer scale is sufficient for setting requirements on the mirror strokes.
