Improvement of spatial resolution in the distributed analysis on Brillouin dynamic grating (BDG) in a polarization-maintaining fiber (PMF) is demonstrated using a differential measurement (DM) sche…
Optical fiber sensors based on Brillouin scattering were first introduced over three decades ago, and various types of distributed sensing schemes have been developed. The Brillouin optical correla…
A single-mode fiber-based polarization-independent Brillouin optical correlation domain analysis system is experimentally demonstrated by applying orthogonally polarized probe sidebands. The Brillo…
Differential measurement (DM) is a modified lock-in detection technique that was introduced to the Brillouin optical correlation domain analysis (BOCDA) for improving the spatial resolution and dyn…
Brillouin optical correlation domain analysis (BOCDA) is an established method for the measurement of Brillouin frequency distribution, where direct modulation of a distributed feedback laser diode…
