工程化光纤光栅应变传感器的制作及其应用

Fabrication and Application of Engineering Fiber Bragg Grating Strain Sensor

分析了适用于动态应变测量的光纤光栅传感器所应满足的条件,并进行了相关实验。在实验的基础上,设计并制作了一种适用于工程化的光纤光栅动态应变传感器。对等强度水泥梁以及实际工程中的卢浦大桥等场合,用该光纤光栅应变传感器与传统的电阻应变片传感器进行了对比验证。实验结果表明。

Analyzed the conditions applying for the dynamic strain measurement of fiber grating sensor, and did some correlative experiments. On the basis of these works,fabricated a type of dynamic strain sensor of fiber grating used for engineering measurement, and contrasted and validated to the results of the traditional resistance strain chip in the laboratory and the practical application situation. The experimental results indicate that the dynamic strain sensor of fiber grating has higher accuracy and excellent practical application.
