Abstract

A fiber optic high-temperature sensor with a low-fineness Fabry-Perot cavity formed by dielectric films on sapphire fiber tip is proposed and demonstrated. Experimental investigation shows that the sensor exhibits a sensitivity of 40.7pm/℃ when the ambient temperature changes from 400℃ to 1000℃.
