EAGLE是目前正在为42米的欧洲天文台超大望远镜（E-ELT）设计的一种多物体三维光谱仪器。EAGLE将使用开环多目标自适应光学（MOAO）在宽（5-10弧分）视场内提供部分AO校正。该方案的新奇在于，在最终建造E-ELT仪器之前，需要进行空中演示。CANARY项目将在4.2米威廉·赫歇尔望远镜上实现MOAO系统的单通道。CANARY项目正在进行分阶段开发计划，首先使用NGS演示低阶开环AO校正，然后使用Rayleigh LGS层析成像演示高阶开环AO校正。这最后阶段还将包括2个低音-高音配置的DM，安装在E-ELT时与EAGLE类似。我们描述了MOAO演示各个阶段的要求、相应的CANARY配置和功能以及各个子系统的当前设计。
EAGLE is a multi-object 3D spectroscopy instrument currently under design for the 42-metre Euro- pean Extremely Large Telescope (E-ELT). EAGLE will use open-loop Multi-Object Adaptive Optics (MOAO) to provide partial AO correction across a wide (5-10 arcmin) field of view. The novelty of this scheme is such that on-sky demonstration is required prior to final construction of an E-ELT instrument. The CANARY project will implement a single channel of an MOAO system on the 4.2m William Herschel Telescope. The CANARY project is undergoing a phased development plan that starts with demonstration of low-order open-loop AO correction using first NGS then Rayleigh LGS tomography, moving to a demonstration of high-order open-loop AO correc- tion using LGS tomography. This final stage will also include 2 DMs in a woofer-tweeter configuration similar to that of EAGLE when installed at the E-ELT. We describe the requirements for the various phases of MOAO demonstration, the corresponding CANARY configurations and capabilities and the current designs of the various subsystems.
