Slope-assisted Brillouin optical correlation-domain reflectometry (SA-BOCDR) is a recently developed structural health monitoring technique for measuring strain and temperature distributions along optical fibers. Although its fundamental operations have been demonstrated with some unique features, no measurement using optical fibers embedded in actual structures has been reported yet. In this work, as a first step to such practical applications, we present an example of SA-BOCDR-based structural diagnosis using composite structure comprising carbon fiber reinforced plastics. The system output well agrees the actual strain distributions. We also detect the breakage of the embedded fiber, showing the potential usefulness of SA-BOCDR in practical fields. |
