在先进的LIGO引力波探测器中，散射光噪声是一种常见的干扰，阻碍了引力波的探测。由低频运动引起的非平稳散射噪声在引力波通道的时频平面上可以被看作是拱形。在本文中，我们描述了LIGO和Virgo从2019年4月到2020年3月的第三次观测运行O3的散射噪声。我们发现至少有两个不同的人口的散射噪声，我们调查的多个起源之一，以及其缓解。我们发现，两个特定的表面之间的相对运动是强烈相关的散射光的存在下，我们实现了一种技术，以减少这种运动。我们还提出了一种算法，使用见证通道来识别这种噪声可以存在于检测器中的时间。
Noise due to scattered light has been a frequent disturbance in the advanced LIGO gravitational wave detectors, hindering the detection of gravitational waves. The non stationary scatter noise caused by low frequency motion can be recognized as arches in the time-frequency plane of the gravitational wave channel. In this paper, we characterize the scattering noise for LIGO and Virgo’s third observing run O3 from April, 2019 to March, 2020. We find at least two different populations of scattering noise and we investigate the multiple origins of one of them as well as its mitigation. We find that relative motion between two specific surfaces is strongly correlated with the presence of scattered light and we implement a technique to reduce this motion. We also present an algorithm using a witness channel to identify the times this noise can be present in the detector.
