Cavity enhanced fibre optic sensors

监测污染场地中有机化合物的传统方法依赖于样品的收集、运输、储存、制备和气相色谱（GC）或高效液相色谱（HPLC）的仪器分析。虽然传统的实验室分析具有较高的准确性、灵敏度和选择性，但它昂贵、耗时且不连续。为了解决这个问题，将开发用于检测有机污染物的腔增强光纤传感器。所提出的传感器能够实时和现场测量。所提出的研究的短期目标是在实验室中设计、构建和表征原型。长期目标将侧重于仪器的小型化，其次是现场测量和远程现场部署。

Conventional methods for monitoring organic compounds in contaminated sites rely on sample collection, transportation, storage, preparation and instrument analysis by gas chromatography (GC) or high performance liquid chromatography (HPLC). Although the conventional laboratory analysis provides high accuracy, sensitivity and selectivity, it is expensive, time-consuming and discontinuous. To address this issue, cavity enhanced fibre optic sensors will be developed for detection of organic contaminants. The proposed sensors are capable of real-time and on-site measurements. The short-term objective of the proposed research is to design, construct and characterize prototypes in the laboratory. The long-term objective will focus on miniaturization of the instrumentation, followed by on-site field measurements and remote site deployment.
