Novel Gas Leak Imager for the Oil & Gas Sector

直接成像气体排放的能力在石油和天然气、工作场所内的健康和安全、环境监测、安全和过程控制等领域有着重要的应用。我们的目标是开发一个主动的，低成本的气体成像仪使用激光照明源和单像素摄像系统。该成像设备是基于压缩感测，仅使用耦合到空间光调制器的单个像素检测器，类似于数字数据投影仪中使用的。依靠单个像素，而不是专业的红外探测器阵列，意味着开发的系统可以非常低的成本。至关重要的是，它可以一直扩展到红外，目前没有成本效益的成像解决方案。

The ability to directly image gas emissions has significant application in areas as diverse as oil & gas, health andsafety within the workspace, environmental monitoring, security and process control. Our aim is to develop anactive, low-cost gas imager using a laser illumination source and a single pixel camera system. The imagingdevice is based compressive sensing using only a single pixel detector coupled to a spatial light modulator,similar to that used in digital data projectors. The reliance on a single pixel, rather than specialist infrareddetector arrays, means the system developed can be extremely low-cost. Crucially, it can be extended all theway into the infrared where currently no cost-effective imaging solutions are available.
