Performance analysis simulation and experimental results of low-order adaptive optics systems in conjunction with speckle post-processing

摘要

Abstract: It has been recognized for some time that full-order adaptive optics systems can provide considerable improvement in the performance of astronomical imaging systems. However, as 4-m-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 simulation 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. !12
