Dynamic Strain Measurement Using Brillouin Optical Time-Domain Reflectometry
… The Brillouin optical time-domain reflectometry (BOTDR) has the advantages of single-end access and simple operation at the construction site, which makes it very popular in civil engineering applications. Furthermore, the demand of the dynamic sensing of strain information is becoming stronger …

Time-Frequency Localisation of Distributed Brillouin Optical Time Domain Reflectometry
… the Brillouin Optical Time Domain Reflectometry (BOTDR) takes the advantages of obtaining full frequency spectrum to provide strain and temperature information along the optic fibre. The key parameters of distributed fibre optic sensors, spatial and frequency resolution, are strongly linked with …
