Abstract

A novel temperature-independent strain sensor system that combines the spliced fiber gratings and an interferometric wavelength difference measuring technique is presented. The interferometric technique uses the unbalanced Mach-Zehnder interferometer with an easy and new amplitude monitoring method rather than conventional phase measurements. To prove the same temperature characteristics of different-diameter gratings temperature responses of four different diameter fiber gratings written on the same material fibers was measured and the results were all the same to be 10.6±0.05 pm/°C.
