开环自适应光学已经成功地在天空中演示了几个小组，包括全层析MOAO演示使用CANARY。MOAO仪器，如RAVEN将提供第一个天文科学和其他计划的仪器，旨在扩展开环AO性能和校正字段的数量。这些计划中的系统中的许多依赖于断层摄影开环LGS波前感测的使用。在这里，我们提出的结果，从组合NGS/LGS层析CANARY系统，然后比较NGS和基于LGS层析系统的性能。我们确定了主要的系统性能驱动因素，并强调了一些潜在的路线，进一步利用开环断层AO。
Open-loop adaptive optics has been successfully demonstrated on-sky by several groups, including the fully tomographic MOAO demonstration made using CANARY. MOAO instrumentation such as RAVEN will deliver the first astronomical science and other planned instruments aim to extend both open-loop AO performance and the number of corrected fields. Many of these planned systems rely on the use of tomographic open-loop LGS wavefront sensing. Here we present results from the combined NGS/LGS tomographic CANARY system and then compare the NGSand LGS-based tomographic system performance. We identify the major system performance drivers, and highlight some potential routes for further exploitation of open-loop tomographic AO.
