- 論文の詳細を見る
We have performed a measurement of Bragg wavelength distribution in a long-length fiber Bragg grating (FBG) with kHz order sampling rate. We have also realized the total distribution measurement with a repetition rate faster than 1 Hz. The proposed sensing system is based on a reflectometry technique ``synthesis of optical coherence function''. The advantage of this system is the capability of random access distributed measurement and fast speed interrogation. At two points of a long-length FBG, we have performed the reflection spectrum variation measurement when an 80 Hz vibration is applied to part of the FBG.
