We are entering the era of Extremely Large Telescopes (telescopes with primary mirrors greater than 20m in diameter), and in order to make the most of these massive machines, we will need to incorporate Adaptive Optics (AO) systems to compensate for turbulence in the atmosphere. AO on 10m class telescopes has come a long way in the past decade. Images from the ground are in some cases surpassing those coming from the Hubble Space Telescope. However, as these AO systems improve, new factors begin to limit their performance. One factor that is currently limiting some of the best AO systems is the quality of their calibration procedures. I propose to support three graduate students (co-supervised with other faculty from the University of Victoria Physics and Astronomy Department) over the next three years in order to tackle some specific challenges of calibrating the next generation of AO systems. In particular, the students will have access to the CFI-funded Raven Multi-Object AO (MOAO) technical and scientific demonstrator. Raven is being built in a partnership between the UVic AO Lab, NRC HIA, the Subaru Observatory in Hawaii, and the National Institute of Optics (INO) in Quebec. The goal of the project is to design and build the first scientifically useful MOAO system in Prof. Colin Bradley's UVic AO Lab, and then transport and use it on the Subaru telescope in Hawaii by 2014. Students who undertake the work of this proposal will explore "open loop" calibration techniques through a multi-tiered effort of simulation, lab experimentation, and deployment in Raven for on-sky tests. Students will have other opportunities to explore issues of AO calibration at HIA, where a multi-conjugate AO test bench is being built for the express purpose of learning how to best calibrate the Thirty Metre Telescope first light facility AO system, NFIRAOS. Students with this type of training will be highly desirable employees either in academia or in industry.

我们进入了极大的望远镜时代（直径大于20m的望远镜的望远镜），为了充分利用这些巨大的机器，我们将需要合并自适应光学（AO）系统以补偿大气中的湍流。在过去的十年中，AO在10m级望远镜上已经走了很长一段路。在某些情况下，地面的图像超过了来自哈勃太空望远镜的图像。但是，随着这些AO系统的改善，新因素开始限制其性能。目前限制一些最佳AO系统的一个因素是其校准程序的质量。我建议在未来三年内支持三名研究生（与维多利亚大学物理与天文学系的其他教师共同监督），以应对校准下一代AO系统的一些具体挑战。特别是，学生将可以使用CFI资助的乌鸦多对象AO（MOAO）技术和科学演示者。 Raven是在UVIC AO实验室，NRC HIA，夏威夷的Subaru天文台和魁北克国家光学研究所（INO）之间建立的。该项目的目的是在Colin Bradley教授的UVIC AO实验室中设计和建立第一个科学有用的MOAO系统，然后到2014年在夏威夷的Subaru望远镜上运输并使用它。进行该提案工作的学生将探索“开放循环”的校准技术，通过多层次的测试进行模拟，并执行实验室，并执行实验，并执行狂欢，并在狂欢中进行狂欢，并在狂欢中进行狂欢，并探索。学生还将有其他机会探索HIA的AO校准问题，该问题是为了实现如何最好地校准如何最好地校准30米望远镜的第一轻型设施AO系统NFIRAOS的明确目的。接受此类培训的学生在学术界或行业中都是非常可取的员工。
