悬点干涉仪（SPI）是用于激光干涉引力波探测器的一种高性能主动隔振方案。通过在干涉仪反射镜的悬挂点处安装辅助干涉仪，该技术有助于降低地震噪声并提高干涉仪的稳定性。我们现在正在构建一个法布里-珀罗干涉仪配备了SPI测试SPI的有效性。我们报告的实验和初步结果，证明约20分贝的振动衰减的SPI低于2赫兹的当前状态。
A suspension point interferometer (SPI) is a high-performance active vibrationisolation scheme for laser interferometric gravitational wave detectors. By making use of auxiliary interferometers installed at the suspension points of the interferometer's mirrors, this technique helps to reduce the seismic noise and to improve the stability of the interferometer. We are now constructing a Fabry-Perot interferometer equipped with an SPI to test the effectiveness of the SPI. We report on the current status of the experiment and preliminary results that demonstrate about 20 dB of vibration attenuation by the SPI below 2 Hz.
