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

近年来，样品的拉曼分析已成为各种部门越来越感兴趣的。特别是对于气体配方，拉曼观测提供了更大的灵活性和接近真实的时间分析。然而，这种技术的最常见的实现往往缺乏例如气相色谱仪或IR吸收光谱的灵敏度，限制了对工业应用的吸引力。在这项研究中，我们将着眼于推进微结构光纤的发展，以生产一种新的传感器，其中高灵敏度的气相拉曼测量可以进行。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，其灵敏度大大提高。
