H. Lee, N. Hayashi, Y. Mizuno, and K. Nakamura, “Slope-assisted Brillouin optical correlation-domain reflectometry: proof of concept,” IEEE Photon. J., vol. 8, no. 3, 6802807 (2016).
Exploiting the slope of the Brillouin gain spectrum, we develop a new configuration of Brillouin optical correlation-domain reflectometry, which can measure strain (or temperature) and optical loss distributions simultaneously with a high sampling rate. The strain, temperature, and loss dependence coefficients of the output signal are measured to be 1.95 × 10−4 dB/με, 4.42 × 10−3 dB/K, and 0.191, respectively, which are consistent with the theoretical predictions. We also verify the basic operation of simultaneous measurement of the three parameters.
