Real-time gas detection and monitoring (Methane, Sulphur oxides, …)
Remote sensing using Fourier Transform Infrared Spectroscopy (FTIR) is a non-invasive technique to detect and identify gases in real-time. Hyperspectral imaging within the two atmospheric windows of the thermal infrared (TIR) spectral region (MWIR: 3 – 5 µm and LWIR: 8 – 14 µm) allows to remotely analyse gases for environmental and industrial applications. This offers a wide range of opportunities such as methane emission monitoring, forest fire monitoring, gas leak detection, pollution monitoring, analyses of smokestacks or flare measurements, or the monitoring of greenhouse gas emissions. Extensive possibilities of hyperspectral remote sensing of gases in the MWIR and LWIR is based on a wide variety of infrared-active chemical compounds: water vapour (H2O), carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4), carbon monoxide (CO), carbonyl sulfide (COS), nitrogen oxides (NOX), sulphur oxides (SOX), and many more.
