Abstract: Distributed fiber-optic vibration sensors receive extensive investigation and play a significant role in the sensor panorama. Optical parameters such as light intensity, phase, polarization state, or
The vibration error mathematical model of all fiber optical current sensor (FOCS) is established.
The generated optical pulses travel through the sensing fiber, where vibration-induced Rayleigh back-scattering is detected by an Photodiode (PD), digitized by an Analog-to-Digital Converter (ADC), and
The sensing system takes the fiber as sensors and has the advantages of being flexible and straightforward to build, and being easy to operate and maintain. It can be used in harsh
In this paper, we propose a modulation - demodulation method based on dual closed-loop feedback to measure the occurrence of sudden vibrations without affecting current measurement.
This work presents the design and test of a fiber optic-based one-axes accelerometer. This device is a reflexive-optical accelerometer and implements a membrane for the seismic mass.
In this work, we propose a novel forward-transmission fiber-optic vibration sensing technique based on Time Delay Interferometry (TDI), originally developed for space-based
Three sensors presented make use of non-contact vibration measurement method with plastic fiber using distinct designs, improvement of the sensor response and advantages of one
