A new multiplexing scheme of fiber Bragg gratings (FBGs) sensing system is presented. Each sensing element is a pair of identical FBGs, with one working as sensing FBG and the other working as a reference. Multiplexing of the FBG pairs is achieved based on optical low coherence technology. A measurement of strain is demonstrated to verify good performance of the system. © 2008 Wiley Periodicals, Inc.
