悬点干涉仪（SPI）是一种用于主动隔振的辅助干涉仪，安装在干涉引力波探测器反射镜的悬点上。我们构建了一个原型法布里-珀罗干涉仪配备了SPI和观察振动隔离的光谱和传递函数。主干涉仪的噪声频谱在1Hz以下降低了40 dB。传递函数测量表明，SPI也产生了良好的振动抑制超过1 Hz。这些结果表明，SPI可以提高干涉仪的灵敏度和稳定性。(C)2004 Elsevier B. V.保留所有权利。
A suspension-point interferometer (SPI) is an auxiliary interferometer for active vibration isolation, implemented at the suspension points of the mirrors of an interferometric gravitational wave detector. We constructed a prototype Fabry-Perot interferometer equipped with an SPI and observed vibration isolation in both the spectrum and transfer function. The noise spectrum of the main interferometer was reduced by 40 dB below 1 Hz. Transfer function measurements showed that the SPI also produced good vibration suppression above 1 Hz. These results indicate that SPI can improve both the sensitivity and the stability of the interferometer. (C) 2004 Elsevier B.V. All rights reserved.
