Adaptive Optics simulations for the European Extremely Large Telescope

摘要

In this article we summarize the parameter space exploration for several adaptive optics systems for a 42-m European Extremely Large Telescope. These systems are modular, and based on a various number of identical high order wavefront sensor. We explore a single natural guide star single conjugate AO and multi-laser guide star systems: ground-layer AO, laser-tomography AO, and multi-conjugate AO. The performance estimates are given in terms of Strehl ratio or, for the GLAO system in terms of ensquared energy.
