Review of Noise Suppressing Technologies for Gravitational-Waves Detection
【摘要】 近年来,微弱引力波探测取得了重要进展。针对引力波测量中的噪声抑制问题,综述了引力波探测的棒状引力波探测器、地面激光干涉仪、空间激光干涉阵列等几种典型方法,解释引力波探测原理,介绍各种引力波探测方法中热噪声、散粒噪声和杂散气体噪声等噪声来源,阐述噪声抑制方法,并介绍四重悬挂、信号重循环、压缩太光场等新型噪声抑制技术。针对空间引力波探测,重点关注时间延迟干涉和锁臂技术等与地面探测方法不同的噪声抑制技术。
【Abstract】 Gravitational waves(GWs) detection have received significant progress in recent years. With the development of noise suspension techniques for GWs detection, this research aimed at facilitating relevant research and introduces classic methods of GW detection, such as Weber bar, ground laser interferometer, and space laser interferometer array. This research briefly explains their principles and elaborating the noise-suppressing means for both groundbased and spaceborne detectors, including quadruple suspension, dual recycling, squeezed light, arm-locking and time-delay interferometry.
