Seismic Observation and Analysis Based on Three-Component Fiber Optic Seismometer
IEEE Access, 2020Co-Authors: Yue Yang, Zhongmin Wang, Tianying Chang, Junjie Chen, Guodong Zheng, Hong-liang CuiAbstract:We demonstrate a three-Component Fiber optic seismometer for seismic observation, with no electronics in the sensor probe, but relying exclusively on optical Fiber in the form of an unbalanced Michelson interferometer, with state-of-the-art performance characteristics. The Fiber optic seismometer system is installed in the seismic observation cave at the Earthquake Administration Bureau of Jilin Province, in Changchun, Jilin, China, and has been operating without interruption for more than a year. Two minor earthquakes of different magnitudes recorded by the three-Component Fiber optic seismometer are analyzed and discussed in detail from the perspectives of time domain and frequency domain signal quality and fidelity. In addition, the recording results of the Fiber optic seismometer are compared with those of the traditional electrical-mechanical seismometer co-located at the observation site. Actual observational results of the seismic events show that the three-Component Fiber optic seismometer can record the seismic waves clearly, with comparable performance as the conventional seismometer.

Ultra-Low-Frequency Tri-Component Fiber Optic Interferometric Accelerometer
IEEE Sensors Journal, 2018Co-Authors: Jiandong Chen, Yue Yang, Zhongmin Wang, Tianying Chang, Gao Wenzhi, Hong-liang CuiAbstract:We demonstrate a high-performance ultra-low-frequency tri-Component Fiber optic interferometric accelerometer (FOIA), designed particularly for application in seismic observation of ocean-floor deployment, with high sensitivity, low noise level, and large dynamic range. Experimental results show that the sensitivity of the FOIA is 57 dB re rad/g, and the noise levels of the three orthogonal Components are 0.163, 0.181, and $\mathrm {0.153~ \mu g}$ , respectively, within the operating frequency band (0.005–50 Hz). The dynamic range of the system is higher than 117.03 dB. Actual observational results of an M4.3 seismic event show that the prototypical system can clearly record the seismic wave, with unambiguous demarcation of S-wave and P-wave, and locate the hypocenter of the earthquake.
