开发了一种基于马赫曾德尔干涉仪和镀钯（Pd）薄膜光纤布拉格光栅的光纤氢气传感器，可同时测量氢气和温度，可有效消除温度交叉敏感性。测量了传感器对0~8%不同氢气体积比、环境温度23~63℃的响应，所得结果与计算值吻合较好。该传感器结构紧凑、工作可靠，适用于氢气实时监测系统。 (C) 2014 Elsevier B.V. 保留所有权利。
An optical fiber hydrogen sensor based on Mach-Zehnder Interferometer and fiber Bragg grating coated with palladium (Pd) film is developed for simultaneous hydrogen and temperature measurement, which can effectively eliminate the temperature cross-sensitivity. The sensor's responses to different hydrogen volume ratios ranging from 0 to 8% are measured, with the environmental temperature varying from 23 to 63 degrees C, and the results obtained are in good agreement with the calculated values. Such a sensor is compact in structure, reliable in operation and hence suitable for real-time hydrogen monitoring system. (C) 2014 Elsevier B.V. All rights reserved.
