Dual-laser Brillouin optical correlation-domain reflectometry

We develop a new configuration for Brillouin optical correlation-domain reflectometry (BOCDR), termed dual-laser BOCDR. This method enables distributed strain and temperature measurement by sweeping the relative phase between the frequency-modulated pump and reference laser outputs. During operation...
