    摘要
  • 摘要: 演示了两种利用光纤侧边抛磨技术制备的用于醋酸浓度检测的光纤传感器。其中一种光纤传感器采用轮式抛磨法对光纤光栅的光栅区包层进行侧边抛磨加工而成，将醋酸溶液覆盖于光纤光栅的抛磨区，利用侧边抛磨光纤光栅反射峰波长的变化对醋酸浓度进行测量；另一种光纤传感器采用轮式抛磨法对普通单模光纤包层进行侧边抛磨加工而成，将醋酸溶液覆盖于光纤抛磨区，利用抛磨光纤插入损耗的变化对醋酸浓度进行测量。两种光纤传感器的实验都表明：光纤包层抛磨表面与纤芯的距离越小，测量分辨率越高。剩余包层厚度为0m的侧边抛磨光纤光栅传感器测量醋酸溶液浓度分辨率为6.67%；剩余包层厚度为0.5m的侧边抛磨光纤传感器测量醋酸溶液浓度分辨率为0.55%。
    Abstract: Two kinds of optical fiber sensors fabricated by fiber side polishing technique are proposed and demonstrated experimentally to measure the concentration of acetic acid. One of them is a side polished fiber Bragg grating sensor, whose cladding in the region of fiber Bragg grating is side polished. Because its reflective Bragg wavelength shifts when polished region is overlaid with different concentrations of acetic acid, the concentration of acetic acid could be measured.The other kind is a side polished single mode fiber sensor, whose part of cladding is side polished. The concentration of acetic acid could be measured by the transmitted optical power when polished region is overlaid with acetic acid. The resolution of side polished fiber Bragg grating sensor with a residual thickness of 0m is about 6.67%. The resolution of side polished single mode fiber sensor with a residual thickness of 0.5m is 0.55%.
