【摘要】 报道了采用预应变技术制作的一种结构简便而新颖实用的光纤光栅传感探头及其对温度和应变的响应特性。该方法能使一根光纤光栅产生两个以上的反射峰 ,因此能解决温度和应变测量时存在的交叉敏感问题。在测量范围内 ,应变和温度响应曲线具有良好的线性。更多还原

【Abstract】 A simple and practical fiber grating sensor for strain and temperature measurement is presented in this paper. By using prestrain technique, two Bragg wavelengths were created by one fiber Bragg grating, and the cross sensing effect was eliminated. Linear responds to strain and temperature were achieved in the measurable ranges.更多还原
