Brillouin scattering in plastic optical fibers - Application to distributed strain and temperature sensing

摘要

After briefly reviewing the fundamental properties of Brillouin scattering in plastic optical fibers (POFs) at 1.55μm, including a so-called "memory" function, we present our latest experimental results on POF-based distributed Brillouin sensing of strain and temperature with a centimeter-order spatial resolution and a high signal-to-noise ratio. Our efforts to simplify the setup are also presented. Besides, a newly observed phenomenon called "POF fuse" is reviewed.
