摘要:
通过氢氟酸腐蚀提高光纤布拉格光栅的应变灵敏度,再把腐蚀后的光纤光栅封装在铝套管中,结合这2种增敏效应,得到了具有更大更灵活的温度灵敏度的光纤光栅,并分析了这种封装结构的温度增敏原理.实验表明,封装后的光纤光栅在20~90 ℃温度范围内,其等效温度灵敏度比普通光纤光栅提高了约5.53倍,比直接铝套管封装的光纤光栅提高了约1.72倍,而且封装后的光纤光栅温度特性曲线具有很好的线性度,达到了0.997 3,并且这种封装可以保护光纤光栅,结构简单,实用性强.
Abstract:
By combining the advantages of etching fiber Bragg grating(FBG)by HF and packaging it in an aluminum tube, an improved temperature-sensitivity of FBG is achieved, which is analyzed theoretically and experimentally. The experimental results show that with this technology, in 20 to 90 ℃ the equivalent temperature sensitivities of the etching packaged FBG and the direct aluminum packaged FBG can be respectively increased by about 5.53 times and 1.72 times. Besides, an excellent linearity of 0.997 3 is also obtained. This package method is simple, convenient for practical use. Moreover, the FBG can well be protected by this kind of package.
