Abstract
Presented herein are systems and methods directed to a multispectral absorption-based imaging approach that provides for rapid and accurate detection, localization, and quantification of gas leaks. The imaging technology described herein utilizes a scanning optical sensor in combination with structured and scannable illumination to detect and image spectral signatures produced by absorption of light by leaking gas in a quantitative manner over wide areas, at distance, and in the presence of background such as ambient gas and vapor. Moreover, the specifically structured and scannable illumination source of the systems and methods described herein provides a consistent source of illumination for the scanning optical sensor, allowing imaging to be performed even in the absence of sufficient natural light, such as sunlight. The imaging approaches described herein can, accordingly, be used for a variety of gas leak detection, emissions monitoring, and safety applications.
