| 摘 要： | 报道利用预曝光技术制备的复合结构光纤光栅传感器。提出利用预曝光技术使某一小段光纤的折射率变大,而后在预曝光部分和未曝光部分的交接处一次性写入光栅,即可得到具有两个透射峰的透射谱。实验研究了该复合结构光纤光栅在温度和应力传感上的应用。实验结果表明,利用该复合结构光纤光栅可以实现温度与应变的同时测量。

| Abstract: | A composite fiber Bragg grating based on pre-exposure technology is described in this paper. The FBG was imprinted on the joint part of the pre-exposure section and un-pre-exposure section of the fiber. Due to the difference of the index between the two sections, the FBG has two reflection peaks at different wavelengths. The composite FBG is investigated experimentally for sensor applications. The experimental results show that the FBG can be used to measure temperature and strain simultaneously. |
