论文摘要
Microarcsond（UAS）天文学是一种必不可少的技术，可检测类似地球的系外行星，充分表征超球星轨道并测量其质量 - 对评估其居住性的重要性。高度准确的星体测量还可以探测暗物质，早期宇宙，黑洞和中子星的性质，从而为新的天体物理学提供独特的数据。本文介绍了校准探测器和场畸变的技术，用于在6 m望远镜上使用焦平面阵列检测器实现狭窄的场相对星形法。
Microarcsecond (uas) astrometry is an indispensable technique to detect earth-like exoplanets, fully characterize exoplanetary orbits, and measure their masses --information critical for assessing their habitability. Highly accurate astrometric measurements can also probe the nature of dark matter, the early universe, black holes, and neutron stars, thus providing unique data for new astrophysics. This paper presents technologies of calibrating detectors and field distortions for achieving narrow field uas relative astrometry with a focal plane array detector on a 6 m telescope.
