Interrogation system for a temperature sensor based on a fiber Bragg grating made in a tapered fiber

The sensor is based on a chirped fiber grating made in a fiber tapered by fusion. The grating has a metallic jacket and acts as sensor element by comparison with the second grating that provides a reference signal. The sensor is interrogated by measuring the power reflected by the two gratings. The system has an accuracy of 0.05°C over a linear operation range of more than 10°C that can be adjusted in the fabrication process.
