本文介绍了Gemini近红外成像仪(NIRI)的基本设计,并讨论了其功能。NIRI提供三种不同的像素尺度,以匹配双子望远镜的不同操作模式,并允许偏振和光谱观测。它配备了红外仪器波前传感器(OIWFS),即使在高度模糊的区域也可以进行倾斜和聚焦校正。科学探测器阵列是Aladdin II InSb 1024 × 1024像素器件,灵敏度为1.0至5.5 μm。
This paper presents the basic design of the Gemini Near‐Infrared Imager (NIRI) and discusses its capabilities. NIRI offers three different pixel scales to match different operating modes of the Gemini telescope and allows polarimetric and spectroscopic observations. It is equipped with an infrared on‐instrument wave‐front sensor (OIWFS) to allow tip‐tilt and focus correction even in highly obscured regions. The science detector array is an Aladdin II InSb 1024 × 1024 pixel device sensitive from 1.0 to 5.5 μm.
