我们讨论了波前传感在近红外（IR）波长的低噪声探测器技术，最近成为可用的优势。本文研究了激光引导星星（LGS）自适应光学（AO）的低阶传感和自然引导星星（NGS）自适应光学的高阶传感。然后，我们转向近红外传感的应用与W。M.凯克天文台（WMKO）用于科学的AO系统，并作为极大望远镜（ELT）上类似系统的演示器。这些演示是基于LGS AO近红外倾斜焦点传感器和我们的合作，以实现近红外金字塔波前传感器（PWFS）的NGS AO L波段日冕成像调查，以确定系外行星候选人。
We discuss the advantages of wavefront sensing at near-infrared (IR) wavelengths with low-noise detector technologies that have recently become available. In this paper, we consider low order sensing with laser guide star (LGS) adaptive optics (AO) and high order sensing with natural guide star (NGS) AO. We then turn to the application of near-IR sensing with the W. M. Keck Observatory (WMKO) AO systems for science and as a demonstrator for similar systems on extremely large telescopes (ELTs). These demonstrations are based upon an LGS AO near-IR tip-tilt-focus sensor and our collaboration to implement a near-IR pyramid wavefront sensor (PWFS) for a NGS AO L-band coronagraphic imaging survey to identify exoplanet candidates.
