Abstract(in Japanese) (See Japanese page)
Abstract(in English) Mechanically long period fiber grating (MLPFG) with a heat-shrinkable tube has some advantages that it is cheap and fabrication is easy. MLPFG with a large polarization dependent loss (PDL) occurred due to fabrication technique can be applied to the vibration sensors. In this report, we clarify experimentally the PDL of our MLPFG against the temperature and pressure. We also propose the vibration sensing systems utilizing the MLPFG and confirm the usefulness of our present system. Moreover, we clarify that the vibration frequency from a few Hz to 8 kHz can be estimated by the power spectrum and that the disturbances applied to the fiber can be successfully detected from the time waveform. We clarify the applications of MLPFGs to the health monitoring and security.
