摘要:A novel high sensitivity pressure sensor based on all-fused-silica Extrinsic Fabry-Pérot optical fiber interferometer, which exhibits extreme low temperature dependence, has been developed. The sensor can excellently operate with a sensitivity of 5.18nm/KPa (0.75nm/psi), a resolution of 38Pa (0.005psi). Due to epoxy-free bonding and reserving a vent hole between the fiber and the ferrule in the process of laser heating fusion bonding, the temperature dependence is significantly reduced to the 0.011nm/℃, and pressure measurement error is 0.021KPa/℃ (0.003psi/℃). The operating point doesn’t shift with backpressure change due to the vent hole. The sensor may be suitable for liquid measurement, environmental monitoring and other industrial applications in harsh environment.
