Advanced Raman gas sensing using Microstructered Fibres

近年来，样品的拉曼分析越来越受到各行各业的关注。特别是对于气体配方，拉曼观测提供了更大的灵活性和近乎实时的分析。然而，这项技术的最常见实施往往缺乏如气相色谱或红外吸收光谱那样的灵敏度，限制了其在工业应用中的吸引力。在这项研究中，我们将推动微结构光纤的发展，以生产一种新的传感器，在这种传感器中可以进行高灵敏度的气相拉曼测量。这种方法将导致开发一种新的紧凑型气相拉曼传感器，与经典的拉曼仪器相比，它的灵敏度有很大的提高。

In recent years Raman analysis of samples has become of increasing interest to a variety of sectors. For gasformulations in particular, Raman observation offers greater flexibility and near real time analysis. However themost common implementations of this technique often lack the sensitivity of e.g. Gas Chromatographs or IRabsorption spectroscopy, limiting the appeal to industrial applications. In this study we will look to advance thedevelopment of Microstructured Optical Fibres to produce a new sensor in which high sensitivity gas phaseRaman measurements can be made. This approach will lead to the development of a new compact gas phaseRaman sensor with greatly improved sensitivity compared to classical Raman instruments.ject Summary
