光纤化学传感是新兴传感器技术中最有趣的一种。作为光载体的光纤赋予化学传感器几个有吸引力的特征。光纤允许通过长距离传输光信号，具有低功率损耗和最小或没有由于环境电噪声或电磁干扰引起的损坏。因此，光纤和光纤传感器非常适合于远程监控。光纤还在传感端提供了完全的电隔离，从而使该设备在爆炸性环境和体内医学应用中使用安全。小的物理尺寸使光纤小型化，并允许传感器的几何灵活性。可以使用这些设备进行实时在线分析。光纤的鲁棒性允许换能器在恶劣环境中操作，并且光纤的相对低的成本为感测装置带来了经济优势。与许多其他化学传感器一样，这些传感器可以多路复用以增强其多功能性。
Chemical sensing with optical fibres is one of the most interesting of the emerging sensor technologies. Optical fibres, which act as light carriers, impart several attractive features to the chemical sensor. The optical fibre allows the transmission of optical signals through great distances with low power loss and minimum or no corruption due to ambient electrical noise or electromagnetic interference. Thus optical fibres and hence optical-fibre transducers are ideally suited for remote monitoring. The optical fibre also bestows total electrical isolation at the transducing end, thus making the device safe for use in explosive environments and inin-vivomedical applications. The small physical dimensions lend the fibre to miniaturization and allow geometric flexibility for the transducer. It is possible to carry out real-time, on-line analysis with these devices. The robust nature of the optical fibre allows the transducer to be operated in hostile environments and the relatively low cost of the fibres introduces an economic advantage to the sensing device. Like many other chemical sensors, these transducers can be multiplexed to enhance their versatility.
