Y. Suzuki, Y. Mizuno, and H. Lee, “Enhancement of loss point detection accuracy by double-slope-assisted Brillouin optical correlation-domain reflectometry,” IEICE Commun. Express, accepted.

We propose and experimentally demonstrate an improved method for detecting loss points in optical fibers using double-slope-assisted Brillouin optical correlation-domain reflectometry (DSA-BOCDR). By utilizing the power ratio of two frequencies with different shifts from the Brillouin frequency shift, we enhance the positional accuracy of loss point detection compared to conventional slope-assisted BOCDR (SA-BOCDR). Our results show that this method can effectively detect loss points with higher accuracy, contributing to the advancement of distributed optical fiber sensing technologies for structural health monitoring.
