Paper 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 this paper we consider some performance metrics for use in determining expected results from a LOAO system when used for long exposure and short exposure (speckle) imaging. The results of computer simulations are compared to data from a recent experiment on the 1.5 meter telescope at the Starfire Optical Range.
