密歇根红外组合器（MIRC）的设计有两个主要目标：1）在近红外线上同时使用所有六个CHARA望远镜成像，2）使用精确闭合相位直接探测“热木星”系外行星。2005年9月，MIRC在Mt. CHARA Array的天空中投入使用。威尔逊，加利福尼亚州，成功地结合从4个望远镜同时发出的光。在简要概述MIRC的功能和设计理念后，我们提供了关键部件的详细描述和实验室测试的结果。最后，我们提出了第一个结果，从调试运行，侧重于工程性能。我们还从第一个晚上记录的数据中展示了显着的天空闭合相位结果，具有有史以来最好的闭合相位稳定性和精度（ΔΦ = 0.03度）。
The Michigan Infrared Combiner (MIRC) has been designed for two primary goals: 1) imaging with all six CHARA telescopes simultaneously in the near-infrared, 2) direct detection of "hot Jupiter" exoplanets using precision closure phases. In September 2005, MIRC was commissioned on-sky at the CHARA Array on Mt. Wilson, CA, successfully combining light from 4 telescopes simultaneously. After a brief overview of MIRC features and design philosophy, we provide detailed description of key components and present results of laboratory tests. Lastly, we present first results from the commissioning run, focusing on engineering performance. We also present remarkable on-sky closure phase results from the first night of recorded data with the best-ever demonstrated closure phase stability and precision (ΔΦ = 0.03 degrees).
