介绍了凯克全天精密自适应光学计划的现状和计划。KAPA包括四个关键的科学计划,升级凯克一号激光制导星星(LGS)自适应光学(AO)设施,以提高图像质量和天空覆盖率,AO遥测为基础的点扩散函数(PSF)估计所有的科学曝光,以及教育部分,重点是扩大妇女和代表性不足的群体参与仪器。为了这次会议的目的,我们将集中在AO设施的升级,其中包括实施一个新的激光,波前传感器和实时控制器,以支持激光断层扫描,激光断层扫描系统本身,并修改现有的近红外倾斜倾斜传感器,以支持多个自然引导星星(NGS)和焦点测量。
We present the status and plans for the Keck All sky Precision Adaptive optics (KAPA) program. KAPA includes four key science programs, an upgrade to the Keck I laser guide star (LGS) adaptive optics (AO) facility to improve image quality and sky coverage, AO telemetry based point spread function (PSF) estimates for all science exposures, and an educational component focused on broadening the participation of women and underrepresented groups in instrumentation. For the purpose of this conference we will focus on the AO facility upgrade which includes implementation of a new laser, wavefront sensor and real-time controller to support laser tomography, the laser tomography system itself, and modifications to an existing near-infrared tip-tilt sensor to support multiple natural guide star (NGS) and focus measurements.
