Paper Abstract

A new type of optical fiber pressure sensor is introduced in this paper. The ratio measurement by means of the sensing optical fiber and the reference fiber with different beginning positions and the technique to improve the stability of the sensor are first discussed. Then the ability to restrain and compensate the interference of the same nature through the double channel ratio measurement is illustrated. Finally, the performance of sensor and its engineering design are discussed.
