摘要:

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.
