Abstract

We report on the experimental demonstration of a switched frequency domain technique for multiplexing of fiber Bragg grating sensors using subcarrier intensity modulation. The technique can be used to address fiber Bragg grating sensor arrays consisting of multiple branches and is capable of multiplexing fiber Bragg gratings of either identical or different Bragg wavelengths. The crosstalk between sensors was found to be negligible.
