AI 中文摘要
地球地震运动的旋转分量是限制地面引力波探测器在10Hz以下频率灵敏度的主要因素之一。核心挑战在于理解地震运动的角自由度以及如何对其进行精确测量，这两个步骤对开发合适的控制系统以抑制地震运动、维持探测器腔的共振至关重要。本综述阐明了旋转地面运动限制探测器灵敏度的原因，概述了过去十年在传感和控制系统方面的技术成就，并简要介绍了该领域未来发展的展望。
英文摘要
The rotational components of Earth's seismic motion are one of the major contributions to limit the sensitivity of terrestrial gravitational-wave detectors at frequencies below 10 Hz. The fundamental challenges lie in understanding the angular degrees of freedom of seismic motion and how they can be accurately measured. These are both crucial steps for developing an adequate control system to suppress seismic motion and maintaining resonance in the detector cavities. This review shows why the rotational ground motion limits the detector's sensitivity and gives an overview of the technological achievements of the last decade on both the sensing and control systems sides. Perspectives on future developments in the field are also briefly illustrated.
