中文摘要：
光纤化学传感器作为传感器的一个重要分支，结合了化学和光学的相关技术，将化学制膜、光纤技术以及化学分析中的分光光度法、拉曼光谱、荧光光谱、折射率检测等方法相融合，以其微型化，抗电磁干扰，传输信息量大，拥有自身参比等特点不断向前发展。简要综述了光纤化学传感技术研究近况和未来的发展趋势。重点对光纤pH 化学传感器、光纤离子化学传感器和光纤气体化学传感器进行了介绍。简要分析了常见的敏感膜制备方法如化学键合法和溶胶凝胶（sol-gel）等方法。新型光纤---微结构光纤的出现为光纤化学传感器开辟了新的发展方向。由于其具有大的内表面积，结构设计灵活多样，光纤内部提供感应场所等特点，快速度成为光纤化学传感器的重要发展方向和研究热点。对微结构光纤衍生而来的新型光纤化学传感器进行了详细评述，最后对光纤化学传感器的未来进行展望。
英文摘要：
The present article provides a brief review of recent research on fiber-optic chemical sensor technology and the future development trends.Especially,fiber-optic pH chemicl sensor,fiber-optic ion chemicl sensor,and fiber-optic gas chemical sen-sor are introducded respectively.Sensing film preparation methods such as chemical bonding method and sol-gel method were briefly reviewed.The emergence of new type fiber-microstructured optical fiber opened up a new development direction for fiber-optic chemical sensor.Because of its large inner surface area,flexible design of structure,having internal sensing places in fi-bers,it has rapidly become an important development direction and research focus of the fiber-optic chemical sensors.The fiber-optic chemical sensor derived from microstructured optical fiber is also discussed in detail.Finally,we look to the future of the fiber-optic chemical sensor.
