Abstract
- Signal demodulation is a key technique for the fiber grating sensor. A new fiber Bragg grating dynamic signal demodulation method based on work-point controlling is present in the paper. The operation principle of the new method and the signal processing scheme of the work-point controlling are expounded systematically. The experiment measurement device is built using the tunable narrow-band laser, which has achieved signal demodulation with high precision. The influence of temperature drift on the measurement results is eliminated with work-point controlling scheme and the ability of dynamic signal detection capability of the fiber grating is greatly improved.
