Paper Abstract

We analyze the use of a single laser or natural guidestar to correct atmospheric distortion for a wide field of view (WFOV) imaging system. We concentrate on the absolute system limits without regard to radiometrics or compensation method by evaluating the best system OTF possible at field points in and beyond the isoplanatic patch. The improvement of OTF at mid- spatial frequencies is several decades over the non-corrected OTF even at field angles of one arc minute, and we conclude that post processing should be able to recover much more information in adaptive optics systems even at wide FOVs than uncompensated systems.
