Abstract
Fiber Bragg grating (FBG) sensing technique is used to measure physical parameters by monitoring wavelength-shift. The key to the high-speed demodulation of FBG sensor signal is how to extract the central wavelength of FBG reflection wave quickly. Compared with other methods, the demodulation technology based on tunable laser has the advantages of high-speed and accuracy. In this paper, in order to solve the problem of inaccuracy in high-speed scanning of tunable laser, a high-speed dynamic calibration scheme is designed. The simulation and experiment are carried out. The relationship between wavelength and control current is accurately obtained.
