Abstract :
A novel multifunctional distributed optical fiber sensor basing on fiber attenuation is proposed to measure ambient temperature and distributed pressure. The sensor is composed of two fibers, the first fiber is used to sense pressure and temperature value while the second fiber is for position information and pressure indication. Distributed sensing is realized based on the attenuation of the second fiber. Pressure position is determined by the outputs of the second fiber. The sensor works at the time-sharing model to realize the multifunctional sensing purpose with the second fiber working as indication. The prototype model of the sensor is developed and tested. The effectiveness of sensor is conformed by experimental results. The proposed sensor presents a novel method for distributed optical fiber sensor
