Abstract
A novel wavelength-division-multiplexed in-fibre Bragg grating sensor system combined with high resolution drift-compensated interferometric wavelength-shift detection is described. This crosstalk-free system is based on the use of an interferometric wavelength scanner and a low resolution spectrometer. A four element system is demonstrated for temperature measurement, and a resolution of ±0.1°C has been achieved.
