Abstract

End-to-End simulations of high strehl Adaptive Optics systems based on Shack-Hartmann and Pyramid wave-front sensors are presented. We limit our study to high temporal bandwidth, in order to focus on the problem of aliasing and detection noise propagation. In particular the effect of spatial filtering is investigated. Some particular features concerning both sensors are highlighted. We analyze the results in terms of residual phase power spectrum.
