Abstract
In this paper, a novel technique for multiplexed fiber Bragg grating (FBG) sensors is proposed. Applying the synthesis of optical coherence function, we can select the signal, which has a specific time delay with the reference light wave, and therefore FBG array with the same reflection wavelength can be used.
