Paper Abstract

It has been recognized for some time that full order adaptive optics systems (one or more actuators per r0) can provide considerable improvement in the performance of astronomical imaging systems. However as four meter class telescopes become the standard for astronomical work it will become more difficult in terms of cost and complexity to build and operate full order AO systems, especially if one is interested in working in the visible. For the past several years we have been developing simula- tion and analysis tools to study AO systems using laser guide stars. This analysis indicates that even low order correction can provide improvements in image quality especially when used in conjunction with computer post processing algorithms. In this paper we expand on past work with computer simulation studies to include the effect of tilt and focus anisoplanitism.
