Error analysis for distributed fibre optic sensing technology based on Brillouin scattering
… work conducted on error analysis for Brillouin Optical Time Domain Reflectometry (BOTDR), a distributed strain sensing technology used for monitoring the structural performance of infrastructures. Although BOTDR has been recently applied to many infrastructure monitoring applications, its …

Distributed Fibre Optic Sensing to Assess Support Reactions and Behaviour of Composite Steel Bridges
… proposed in this investigation involves using distributed fibre optic sensing (DFOS) strain measurements to estimate support reactions in beams through an experimental investigation that involved beam, model bridge, and field load tests. Five steel beams were instrumented with fibre optic …

Time-Frequency Localisation of Distributed Brillouin Optical Time Domain Reflectometry
Distributed fibre optic sensing (DFOS) is essential for structural health monitoring (SHM) of strain changes induced during the lifetime of a structure. Among different DFOS systems, the Brillouin Optical Time Domain Reflectometry (BOTDR) takes the advantages of obtaining full frequency spectrum to …
