Abstract

A distributed fiber optic pressure sensor based on a piece of the photonic crystal fiber (PCF) is proposed and experimentally demonstrated. The sensor is fabricated by splicing the PCF with a single-mode fiber (SMF), and the free end face of the PCF is filmed with a reflectivity of 99%. A Michelson interferometer is formed in the PCF. The pressure position can be located by measuring the phase difference of the interferometer, and the pressure can be interrogated by measuring the amplitude of the optical spectrum. The experimental results show that the pressure and its position along the PCF can be simultaneously interrogated.
