Abstract
Adaptive optics systems that use a single guide star can only accomplish their best atmospheric correction over a small area. Layer oriented MCAO has been proposed for extremely large telescopes as a method to achieve adaptive optics correction over a larger field of view. Diolaiti et al have analyzed the stability and steady-state performance properties of layer oriented MCAO system with a number of (reasonable) simplifying assumptions: no loop delay; no mirror dynamics; continuous and position-independent control action; significantly faster adaptive optics loop than turbulence; and performance assessed by the static response of the closed loop system. This paper will use dynamic analyses to investigate the effects of these assumptions on the overall system performance and stability.
