A Magnetic Field Sensor Based on a Fiber Bragg Grating with a Cantilever Beam
【摘要】 介绍一种新的磁场传感器的原理 ,传感元件为贴在等腰三角梁上的光纤光栅。实验上测得该传感器的灵敏度为 18.1T/nm,与理论值 17.6 T/nm相吻合。
【Abstract】 A novel concept of magnetic field sensor based on a fiber bragg grating (FBG) with an isosceles-triangulated cantilever beam is presented.The experimental sensitivity of the sensor is 18.1 T/nm,which matches reasonably well with the theoretical value 17.6 T/nm.
