[Abstract]:In order to study the fabrication technology of CCFPI sensor with coaxial cable Fabry-Perot Interferometer, the influence of different structural parameters on the signal quality of CCFPI sensor is simulated. It is concluded that the outer diameter of insulation layer of CCFPI reflection point should be in the range of 1.42mm. The length of clamping deformation should not be less than 2 mm, the consistency of reflection point has a significant effect on the signal quality, the linear response of signal frequency shift to cable strain is observed during the cable stretching process, and the CCFPI sensor is fabricated based on the simulation results. The experimental results show that the strain measured by the 1% CCFPI sensor is always in good agreement with the meter. The fitting slope is 1.004 2 and the correlation coefficient is 0.998 67. The measured data of the CCFPI sensor are in good agreement with the fiber grating in the small strain range, which shows that the measurement results of the sensor are true and reliable. At the same time, the CCFPI sensor has a resolution of 110 渭 蔚 and a failure strain of 140,000 渭 蔚.
