A novel technique for fiber Bragg grating sensors is proposed and demonstrated. With this technique, position information from an array of FBG's with similar reflection wavelength can be resolved by using synthesis of optical a coherence function. In this paper, we present basic experiments, in which we successfully demonstrate the multiplexed strain measurement from 3 FBG's having similar reflection wavelength.
