Aging degradation and seismic damage of civil infrastructures have become a serious issue
for society, and one promising technology for monitoring their conditions is optical fiber …

To date, the application of self-sensing or other structural health monitoring (SHM)
technologies in railway sleepers is limited. Development and deployment of smart sleepers …

This book explains physical principles, unique benefits, broad categories, implementation
aspects, and performance criteria of distributed optical fiber sensors (DOFS). For each kind …

Brillouin optical time-domain analysis (BOTDA) requires frequency mapping of the Brillouin
spectrum to obtain environmental information (eg, temperature or strain) over the length of …

Optical fibre sensors based on Brillouin scattering have been vigorously studied in the
context of structural health monitoring on account of their capacity for distributed strain and …

We report a high-spatial-resolution and long-range distributed temperature sensor through
optimizing differential pulse-width pair Brillouin optical time-domain analysis (DPP-BOTDA) …

We propose and demonstrate a dynamic Brillouin optical fiber sensing based on the multi-
slope assisted fast Brillouin optical time-domain analysis (F-BOTDA), which enables the …

We theoretically and experimentally analyze the operation of Brillouin optical correlation-
domain reflectometry (BOCDR). First, we experimentally confirm that BOCDR is not based …

Brillouin optical correlation-domain technologies are reviewed as “fiber optic nerve systems”
for the health monitoring of large structures such as buildings, bridges, and aircraft bodies …

We propose and experimentally demonstrate a chaotic Brillouin optical correlation-domain
analysis system for distributed fiber sensing. The utilization of a chaotic laser with a low …
