並列タイトル等A Study on Brillouin Scattering Properties in Plastic Optical Fibers for Sensing Applications
一般注記Brillouin scattering in plastic/polymer optical fibers (POFs) with high flexibility is applicable to distributed strain and temperature sensing. In this dissertation, first, the author fully investigated their Brillouin scattering properties. For instance, the non-monotonic large-strain dependence of Brillouin frequency shift (BFS) and what is called the BFS hopping phenomenon were experimentally observed, and their origins were clarified. Finally, by exploiting these unique features, he demonstrated POF-based distributed strain and temperature sensing with a high signal-to-noise ratio by use of Brillouin optical correlation-domain reflectometry. He also succeeded in achieving a centimeter-order spatial resolution as well as in simplifying the sensor configuration, opening a promising way to develop practical distributed sensors using POFs.
