Paper Abstract

The method of vibration signal processing for interferometric optical fiber sensor is presented in this paper. For stable vibration, the method of frequency spectra analysis is used. For random vibration, using the system of fiber optic sensor in special coherence combined digital image processing setup and recording to moved number and direction of interferometric fringe and physical formula, collecting and processing image signal of vibration state is presented and professional software is studied and stress-time curve under random vibration state is measured after stress-time curve and vibration frequency for stable vibration were measured where they correspond with theory solution. This research provides a kind of new method for vibration monitoring of structure engineering.
