幸运成像与低阶自适应光学系统的结合在近10年前在帕洛马5米望远镜上得到了非常成功的证明。它仍然是唯一一个在地面望远镜上对微弱的天文目标提供可见光或近红外高分辨率图像的系统。本文将介绍AOLI最初部署在加那利群岛拉帕尔马WHT 4.2米望远镜上的情况。特别是,我们将研究我们的低阶曲率波前传感器的设计和状态,该传感器已被简化以使其更有效,确保覆盖大部分天空,以自然引导星作为参考对象。AOLI使用光学对接的电子倍增CCD来提供2000 x 2000像素的成像阵列。
英文摘要:
The combination of Lucky Imaging with a low order adaptive optics system was demonstrated very successfully on the Palomar 5m telescope nearly 10 years ago. It is still the only system to give such high-resolution images in the visible or near infrared on ground-based telescope of faint astronomical targets. The development of AOLI for deployment initially on the WHT 4.2 m telescope in La Palma, Canary Islands, will be described in this paper. In particular, we will look at the design and status of our low order curvature wavefront sensor which has been somewhat simplified to make it more efficient, ensuring coverage over much of the sky with natural guide stars as reference object. AOLI uses optically butted electron multiplying CCDs to give an imaging array of 2000 x 2000 pixels.
High-Resolution Imaging in the Visible on Large Ground-Based Telescopes
“幸运成像”与低阶自适应光学系统相结合,提供了有史以来在可见光或近红外波段拍摄的微弱天体的最高分辨率图像。本文介绍了一种新的仪器,已经部署在拉帕尔马的WHT 4.2米望远镜,特别强调的光学设计和预测的系统性能。采用光子计数CCD探测器和多平面曲率波前传感器的低阶波前传感器的新设计将使微弱的自然导航星几乎覆盖整个天空。AOLI拥有1024 x 1024个光子计数EMCCD的2 x 2阵列,是新一代高灵敏度、近衍射极限成像系统中的第一个,在地面可见光范围内的分辨率比迄今为止从太空获得的分辨率更高。
