AO Instruments - ESO
The prime objective of the Spectro-Polarimetric High-contrast Exoplanet Research (SPHERE) instrument for the VLT is the discovery and study of new extra-solar giant planets orbiting nearby stars by direct imaging of their circumstellar environment.
第十七期：光学望远镜特辑之凯克望远镜-Keck Telescope - 知乎
凯克望远镜在天文学上提供了最大的潜在灵敏度和清晰度，同时配备最先进的 自适应光学 技术（AO，AdaptiveOptical）以消除大气湍流对像质的影响。 AO通过一面每秒改变2000次形状的变形镜测量并修正大气湍流。 1999年，KeckⅡ望远镜成为世界上第一个开发和安装AO系统的大型望远镜。 与其它大型地面望远镜相比，这一结果使得图像清晰度提高了十倍。 最初，自适应光学依赖于一颗明亮且接近目标天体的恒星发出的光。 但是只有足够多的明亮恒星能让自适应光学校 …

vlt属于地平式望远镜，主结构包含方位轴和高度轴，单个望远镜重约500吨。 方位轴结构由8个推力静液垫支撑，在两个同心轨道上移动，一个内轨和一个外轨，平均直径分别为9米和17.2米。
• ’Discussion for the next AO instrument at the Nasmyth focus on UT4 to make full use of the AOF has started’ ØPlanning for the next VLT AO instrument (STC-568; April
In the following we will concentrate on the VLTI imple-mentation. The main aim of MACAO-VLTI is to feed the VLTI with a corrected wave-front, to improve light injection efficien-cy in the monomode...
Testing the VLT AO facility with ASSIST | Semantic Scholar
2010年7月16日 · ASSIST, The Adaptive Secondary Setup and Instrument STimulator, was developed to provide a testing facility for the ESO AOF and will allow off-telescope testing of three elements of the VLT Adaptive Optics Facility; the Deformable Secondary Mirror (DSM) and the AO systems for MUSE and HAWK-I (GALACSI and GRAAL).
Adaptive Optics for MUSE - SpringerLink
2005年11月11日 · In this article, we present the envisioned adaptive optics (AO) system for MUSE (Multi-Unit Spectroscopic Explorer), a visible light integral field spectrograph for the VLT. Two modes, a low spatial resolution and a high spatial resolution (diffraction limited) have...
NAOS--the first AO system of the VLT: on-sky performance
2003年2月7日 · NAOS is the first adaptive optics system installed at the VLT 8m telescopes. It was designed, manufactured and tested by a french Consortium under an ESO contract, to provide compensated images to the high angular resolution IR spectro-imaging camera (CONICA) in the 1 to 5 μ m spectral range.
In April and August ’03 two MACAO-VLTI curvature AO systems were installed on the VLT telescopes unit 2 and 3 in Paranal (Chile). These are 60 element systems using a 150mm bimorph deformable...
