| Abstract: | As a kind of novel distributed fiber optic sensing technique,Brillouin Optical Time Domain Reflectometer(BOTDR) is introduced in this paper.The distributed fiber optic sensing system based on BOTDR is arranged on a continuously reinforced concrete pavement(CRCP),the strain of the steel and concrete in the CRCP is detected on-line.The experimental results show that the BOTDR technologies demonstrate a wide spectrum of applications in structural health monitoring. |
