Journal ArticleDOI
Distributed Vibration Sensor Based on Coherent Detection of Phase-OTDR
TL;DR: In this paper, a distributed vibration sensor was developed by using heterodyne detection and signal processing of moving averaging and moving differential for the phase optical time domain reflectometry system for detecting pencil break vibration.
Journal ArticleDOI
Novel fiber-optic sensors based on long-period fiber gratings written by high-frequency CO/sub 2/ laser pulses
TL;DR: In this paper, a novel long-period fiber grating (LPFG) fabricated by using a new writing technique that is mainly based on the thermal shock effect of focused high-frequency CO/sub 2/ laser pulses at several kilohertz was reported.
Journal ArticleDOI
Micro Fabry-Perot interferometers in silica fibers machined by femtosecond laser.
TL;DR: Investigation of the strain and temperature characteristics of the two MFPIs with an identical cavity length show that the strain sensitivity of the PCF- based MFPI is smaller than that of the SMF-based M FPI due to their different waveguide structures, while the twoMFPIs have close temperature sensitivities due to the similar host materials.
Journal ArticleDOI
High Sensitivity Distributed Vibration Sensor Based on Polarization-Maintaining Configurations of Phase-OTDR
TL;DR: In this article, a system based on all-polarization-maintaining configurations of the phase-sensitive optical time-domain reflectometry (OTDR) is presented for vibration sensing.
