Abstract
While still in their infancy, adaptive optics systems give rich promise of providing to ground-based and space-based observers the capability to obtain near-diffraction limited images through the earth's atmosphere or though new lower- cost space optical systems. Close study of the images now being obtained with AO systems on ground-based systems, aiming toward the serious photometric use of the current systems, shows that serious image artifacts exist. These affect both the study of morphology and the photometric accuracy. This paper explores the source of these artifacts by analytic modeling of the AO systems, and compares the result of the modeling with data obtained on the telescopes.
