Abstract

Fiber optic sensors are widely used in structure monitoring and smart materials to measure the temperature. In this paper, a novel fiber-mercury temperature sensor (FMTS) is designed and tested. The sensor is made using the surface of the mercury to act as the reflector. The intensity of the reflective light is the function of the distance between the surface of the mercury and the fiber end, which is determined by the thermal extension of the mercury. And different length of the mercury in the capillary defines different sensitivity of the sensor. The modulation function of the sensor is analyzed. Experiment was carried out to evaluate the performance of the sensor, and the results present a good correlation between the theoretical and experimental result.
