The broader impact/commercial potential of this I-Corps project is the development of a lightweight, compact, and stable instrument for gas sensing and can be used, for example, in finding the source of natural gas (methane) leaks. Globally, each year 3% ($30 billion) of natural gas is lost between extraction and use. Methane is a potent greenhouse gas and s significant contributor to climate change so it is important to both regulators and oil and gas companies that gas leaks are able to be found efficiently. There are also public health applications for inexpensive and sensitive trace gas sensing: noxious gases can cause significant health issues and can be indicative of poor air quality.This I-Corps project is based on the development of a lightweight, drone-mounted spectrometer for identifying gases. Each gases has known absorption features in the mid-infrared spectrum allowing for spectroscopic measurements of composition and concentration. This proposed technology creates non-axially-symmetric optics in spectrometers that are more compact than those currently on the market.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个I-Corps项目更广泛的影响/商业潜力是开发一种轻便、紧凑和稳定的气体传感仪器，例如，可以用于寻找天然气（甲烷）泄漏的来源。在全球范围内，每年有3%（300亿美元）的天然气在开采和使用之间损失。甲烷是一种强大的温室气体，是气候变化的重要贡献者，因此对于监管机构和石油天然气公司来说，能够有效地发现气体泄漏非常重要。廉价而灵敏的痕量气体传感也可用于公共卫生：有毒气体可造成严重的健康问题，并可表明空气质量差，I-Corps的这一项目的基础是开发一种轻型、安装在无人机上的用于识别气体的光谱仪。 每种气体在中红外光谱中具有已知的吸收特征，允许光谱测量成分和浓度。该技术可在光谱仪中实现非轴对称光学，比目前市场上的光谱仪更紧凑。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
