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…
We propose and experimentally demonstrate a long-range Brillouin optical correlation domain analysis (BOCDA) system based on distributed Raman amplification and injection-locking to reach over 2.6 …
A distributed ultraviolet sensor based on Brillouin scattering in an azobenzene polymer-coated optical fiber is experimentally demonstrated. A Brillouin optical correlation domain analysis applying…
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…
We present the experimental analysis on the spatial mode structure in a PANDA-type few-mode fiber (PANDA-FMF) by the intermodal operation of Brillouin dynamic grating (BDG). Polarization-maintainin…
We demonstrate the enlargement of sensing range of Brillouin optical correlation domain analysis (BOCDA) system by introducing the first-order distributed Raman amplification. The time-domain data …
We propose a linearly configured Brillouin optical correlation domain analysis system incorporated with time domain data processing, where a fiber under test (FUT) is accessed from single end and m…
