Multi-parameter measurement is important for building health monitoring. In this paper, we use fiber Bragg grating (FBG) and extrinsic Fabry-Perot interferometer (EFBI) sensor to realize the measurement of strain, temperature and vibration. A universal demodulate method, which combines the low coherence interference demodulation of EFBI and fiber Fourier transform demodulation of FBG, is proposed. Thus it is possible to extract the signals from FBG and EFBI parallely with only a Michelson interferometer. A data fusion model is established to process the origin data to get more precise results and distinguish the different parameters. The system is tested on a equi-intensity cantilever, and the results of experiment show that strain and temperature can be obtained efficiently.
