Abstract

Single-crystal sapphire fibers have a very high melting point (up to 2050°C), which renders them a very good candidate for the sensing applications at a very high temperature. We present in this paper the recent work of developing single-crystal sapphire fiber extrinsic Fabry-Pérot interferometric strain sensors based on the whitelight interferometric spectrum demodulation technique. Prototype sapphire strain sensors were fabricated and tested at high temperatures up to 1004°C . The preliminary experimental results indicate that the sensors are promising to be used under high-temperature environments for making strain measurements with the strain measurement resolution of 0.2-µ strain.
