Abstract

Detection, identification, and quantification of exhaust gas emissions is critical to ensure compliance with regulatory guidelines and mitigate damage to the environment. Passive thermal infrared hyperspectral imaging is among the technical solutions that can remotely detect, identify, and quantify multiple gases simultaneously. Telops has recently developed a suite of gas quantification tools designed for use on the Hyper-Cam series of hyperspectral imaging systems. In order to demonstrate the feasibility of quantitative gas measurements in real-world environments, Telops participated in a maritime measurement campaign in 2021. The Telops Hyper-Cam-LW was used to quantitatively measure the SO2 emissions from the main exhaust of a cargo ship transiting the Saint Lawrence Seaway. This work will introduce the fundamental principles underlying gas quantitation using thermal infrared hyperspectral imaging as well as report quantitative gas imaging results generated from the 2021 measurement campaign.
