Abstract

A temperature-sensor system based on low-coherence interferometry with a fiber Mach–Zehnder interferometer as a phase modulator was implemented. A measurement range of 20 to 800 °C with a resolution of 0.025 °C (corresponding to 0.0004 fringe) was achieved with a 1-mm-long fiber Fabry–Perot interferometer as the sensing element.
