Abstract

We describe an interrogation technique for fiber Bragg grating sensors based on serially arranged set of receiver FBG elements, which are used to decode strain induced wavelength shifts of six FBG sensor elements. Each of the receiver elements is wavelength-matched to one of the FBG sensor elements allowing for wavelength discrimination and passive demodulation of individual sensor strain information.
