The sensing properties with strain and temperature of tapered FBG had been researched both theoretically and experimentally. Based on tapered FBG and thin-wall strain cylinder structure  a novel temperature-independent high pressure sensor was fabricated and investigated. The tapered FBG performed as a chirped grating  whose bandwidth and reflection power broadened and increased when the pressure applied on it. Moreover  the bandwidth and the reflection power were temperature-independent. So the value of the strain can be obtained by detecting the reflection power. This method effectively solved the cross-sensitivity problem. The experiment results indicated that this sensor provided a measurement range of 040MPa with a sensitivity of 0.04w/MPa  low cost and good application prospect. 2010 IEEE.
