Abstract
Adaptive optics has been studied for several years as a method to overcome the effects of atmospheric turbulence on ground based astronomy. It is often assumed that full order correction, with one or more actuators per r0, is necessary to achieve any performance improvement in imaging quality with the AO system. Recently it has been shown, both with theoretical analysis and experimental measurements, that even low order adaptive optics (LOAO) can provide image improvements especially when used in conjunction with some sort of computer post processing. In a previous paper we described simulations and experimental results of a LOAO experiment using 25 actuators across a 1.5 meter telescope. In this paper we present performance simulations for a planned experiment with a 163 actuator deformable mirror placed at the pupil of the 3.5 meter telescope at the Phillips Laboratory Starfire Optical Range at Kirtland Air Force Base.
