3-Dimensional Strain Sensor in Fiber Bragg Grating
A 3-dimensional strain sensor with fiber Bragg grating (FBG) was designed and realized.The sensor was based on cylinder structure,with three FBGs fixed on surface of cylinder by 120° angle intervals.This 3D sensor was theoretically demonstrated with material mechanics,and experiment was taken with stress of serials on a random direction.Experiment results show that the sensor can measure strain in any direction in 3-dimension space.The measure results have high linearity and error below 1.58% in measure range of 0-5N,and its′ measure precision can reach 9.2×10-3N.
