A High Precision Fiber Bragg Grating Inclination Sensor for Slope Monitoring

الملخص EN

A high precision and small size Fiber Bragg Grating (FBG) inclination sensor which is used for slope monitoring is proposed in this paper.

The FBG inclination sensor has a pendulum structure for high precision and a circular body for easy installation in the common inclinometer pipe.

The sensitivity of the FBG inclination sensor can reach 400 pm/deg by optimizing its parameters.

The test results show the superior performance of this FBG inclination sensor in terms of static characteristics, and its sensitivity is 406.6 pm/deg.

The comparison experiment shows the static characteristics of the FBG inclination sensor are better than the traditional electrical inclination sensor.
