摘要：

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 thr 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 degrees C has been achieved.
