提高夏克-哈特曼传感器的灵敏度

Increasing the sensitivity of a Shack-Hartmann sensor

Markus Kasper, Douglas Looze, Stefan Hippler, Ric Davies, Andreas Glindemann

摘要:

马克斯-普朗克天文学研究所和地外物理学研究所在西班牙卡拉尔阿尔托的3.5米望远镜上运行着一个带有激光导星的自适应光学系统。该系统被称为ALFA,产生了新的科学成果,并与R波段13等的天然导航星(NGS)配合良好。然而,最终的目标是实现类似的性能与激光制导星(LGS),这是微弱的和扩展。我们介绍了在ALFA实现的夏克哈特曼波前传感器,并提出我们的努力,提高其灵敏度,通过使用先进的质心和波前重建算法。

英文摘要:

The Max-Planck institutes for astronomy (MPIA) and for extraterrestrial physics (MPE) run an adaptive optics (AO) system with a laser guide star at the 3.5 m telescope on Calar Alto, Spain. This system, called ALFA, produces now scientific results and works ex- cellent with natural guide stars (NGS) as faint as 13th magnitude in R-band. The ultimate goal however is to achieve similar performances with the laser guide star (LGS) which is faint and extended. We introduce the Shack-Hartmann wavefront sensor implemented in ALFA and present our efforts in increasing its sensitivity by using advanced centroiding and wavefront reconstruction algorithms.
