作为凯克全天精确自适应光学(KAPA)项目的一部分,激光星象发生器(AG)正在凯克1号望远镜上实施。AG通过将一个22W激光束分成四个等强度的光束,为凯克自适应光学(AO)系统提供四个激光引导星(LGS)。我们提出了KAPA的AG的设计和实现。我们讨论了光学设计和布局,机械设计和制造的细节,以及设计组件以适应凯克望远镜有限的可用空间的挑战。
As part of the Keck All-sky Precision Adaptive optics (KAPA) project a laser Asterism Generator (AG) is being implemented on the Keck I telescope. The AG provides four Laser Guide Stars (LGS) to the Keck Adaptive Optics (AO) system by splitting a single 22W laser beam into four beams of equal intensity. We present the design and implementation of the AG for KAPA. We discuss the optical design and layout, the details of the mechanical design and fabrication, and the challenges of designing the assembly to fit into the limited available space on the Keck telescope.
