论文摘要
我们为低频应用和相应的加速度测量提供了一种新型的光力惯性传感器。该传感器的谐振频率为4.7Hz，机械质量因子为476K，测试质量为2.6克，预计的噪声底部约为5E-11 M S-2。每个root-hz处于1Hz。这种性能以及其尺寸小，重量低，功耗降低以及对环境变量（例如磁场或阻力条件）的敏感性降低，使其成为未来地球任务的有吸引力的技术。在本文中，我们通过与商业地震仪，ANDA数据分析算法直接比较低频地震噪声检测检测低频地震噪声检测的实验证明。
We present a novel optomechanical inertial sensor for low frequency applications and corresponding acceleration measurements. This sensor has a resonant frequency of 4.7Hz, a mechanical quality factor of 476k, a test mass of 2.6 gram, and a projected noise floor of approximately 5E-11 m s-2. per root-Hz at 1Hz. Such performance, together with its small size, low weight, reduced power consumption, and low susceptibility to environmental variables such as magnetic field or drag conditions makes it an attractive technology for future geodesy missions. In this paper, we present an experimental demonstration of low-frequency ground seismic noise detection by direct comparison with a commercial seismometer, anda data analysis algorithms for the identification, characterization, and correction of several noise sources.
