Distributed vibration sensor with a high strain dynamic range by harmonics analysis
Distributed vibration sensor with a high strain dynamic range by harmonics analysis
Distributed vibration sensors (DVSs) have important applications in industrial production. A large strain dynamic range is very important for DVSs, but difficult to achieve as it often requires a complex sensing system or cumbersome data processing. This study shows that the strain dynamic range of the DVS can be improved by analyzing the harmonic numbers in the vibration response spectrum, and the vibration amplitude can be quantitatively measured with a strain resolution of 0.78 με for each additional harmonic. The system and data analysis method can significantly improve the strain dynamic range in comparison with traditional DVS based on the intensity or polarization information.

Abstract
Distributed vibration sensors (DVSs) have important applications in industrial production. A large strain dynamic range is very important for DVSs, but difficult to achieve as it often requires a complex sensing system or cumbersome data processing. This study shows that the strain dynamic range of the DVS can be improved by analyzing the harmonic numbers in the vibration response spectrum, and the vibration amplitude can be quantitatively measured with a strain resolution of 0.78 με for each additional harmonic. The system and data analysis method can significantly improve the strain dynamic range in comparison with traditional DVS based on the intensity or polarization information.
