Abstract
Eight carrier modulated gratings having the same Bragg wavelength but different carrier frequencies were multiplexed together. The gratings were interrogated and the resultant measurements were processed in such a way to separate out the measurand induced changes of each of the differing carrier components corresponding to each sensor grating. The worst-case scenario for measurement error and crosstalk is investigated.
