Abstract

Fiber optic Fabry-Perot sensor has been shown to possess high sensitivity among phase-modulated fiber optic sensors. In the last decade, they have found numerous applications in industry, military, and civil engineering. But they are not easy to manufacture. To avoid the difficult in fabricating the temperature sensor by embedding the gauge in to temperature-sensitive materials, a novel Fabry-Perot sensor is designed and fabricated. The most influential factors of the thermal sensitivity of the sensor are analyzed, which gives the guidelines in design of different sensitivity sensors. Experiments were carried out to verify the theoretical analysis. And the results show that the sensors have good performance and by changing the gauge length the sensitivity of the sensor can be easily controlled.
