提高光纤光栅应变传感和振动传感测量精度的一种方法

摘要

The paper introduces a method using matching twin Fiber Bragg Grating (FBG) in the sensor head, and also adopts matching fiber grating in the measure device. We can double the Microdisplacement of wavelength which is caused by strain, vibration. So the measure precision of this sensor is improved twice.%采用匹配的双光纤光栅组成传感头和采用匹配的光纤光栅组成检测光路，使应变、振动引起的波长移位放大了一倍，从而使这种传感器的测量精度提高一倍.
