A glass fiber reinforced polymer (GFRP) material is a newly developed material for slope
reinforcement. In this study, distributed optical fiber sensors are developed to characterize …

Abstract The Geotechnical Monitoring System (GTMS) based on Distributed Temperature
and Strain Sensing has been used for more than 15 years to mitigate geohazards along …

In the actual structural health monitoring system of suspension bridges, only part of
suspenders tension can be monitored, but not all the suspenders tension can be obtained …

Fiber distributed Brillouin sensing is discussed, focusing mainly on optical correlation
domain techniques. By synthesizing a delta-function like optical coherence function between …

Optical fiber sensors based on stimulated Brillouin scattering in optical fibers have now
clearly demonstrated their excellent capability for long-range distributed strain and …

A novel technique that enables coherent detection of spontaneous Brillouin scattering in the
radio-frequency (< 500 MHz) region with excellent long-term stability has been …

It is known that the ultimate spatial resolution for a Brillouin-based sensor is limited by the
lifetime of the phonons in the fiber that mediate the Brillouin loss process. At optical pulse …

Exact (both analytical and numerical) solutions for steady state stimulated Brillouin
scattering in single mode optical fibers are presented. The resulting solution is compared …

We provide an overview of the use of optical pulse coding to enhance the performances of
long-range distributed optical fiber sensors for strain and temperature measurements. First …

A novel differential-technique Brillouin optical time domain reflectometry with sub-meter
spatial resolution is proposed and demonstrated. By analyzing the time-space related …
