Stability Analysis and Improvement of An Inteferometric Interrogation for Fiber Bragg Grating Sensors
A compensation method with theoretical analysis is proposed to compensate the instability of interrogation by using a pair of fiber Bragg grating (FBG) with different thermal coefficients. The factors that influenced the stability of interrogation had been investigated. Several sensors were installed in Donghai Bridge and formed a sensor network. The signals from sensors were demodulated by the improved interrogator on the final test of Donghai Bridge, which shows good performance.
