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
Abstract. A novel cantilever-type fiber Bragg grating (FBG) mechanical vibration sensor has been proposed with an excellent sensitivity through the use of the mechanical axial property of a
We have proposed a vibration sensor based on a Michelson interferometer. The sensor was developed in the form of a triaxial accelerometer, calibrated, and ultimately validated with
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
The experimental results show that it operates at temperatures up to 600 °C with a sensitivity of 38.66 nm/g and a characteristic frequency of 2446 Hz. This work provides a new
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.
The design of a dual plastic optical fiber (POF) vibration sensor using different fiber pair combinations reported along with necessary theory and experimental results.
Abstract: Distributed optical fiber vibration sensing (DVS) systems offer a promising solution for large-scale monitoring and intrusion event recognition.
