摘要
A hybrid optical fibre sensor composed of a fibre Bragg grating (FBG) and Fabry-Perot (FP) cavity fabricated by chemical etching was proposed for dual-parameter measurement. The temperature characteristics were measured over the range 30100 degrees C. The spectrum of the FP cavity did not shift with temperature, but the sensitivity of the FBG was 9.5 pm/degrees C (linearity, 0.9994). The sensor showed excellent repeatability. Its strain behaviour was examined in the range 0-550 mu epsilon. For the FP cavity, the loading and unloading strain sensitivities were 2.8 and 3pm/mu epsilon, respectively (linearity > 0.9539); for the FBG, these values were both 1.3 pm/mu epsilon (linearity > 0.9994).
