Optical imaging identification of CO2 and SO2 in non-contact detection system using infrared camera

Detection of CO2 and SO2 gases is crucial because they are indicators of volcanic eruption activity. The release of CO2 from the volcano with an increasing concentration is an indicator that an eruption will occur, while the increase in the release of SO2 occurs after the eruption of Merapi.

Zusammenfassung:Detection of CO2 and SO2 gases is crucial because they are indicators of volcanic eruption activity. The release of CO2 from the volcano with an increasing concentration is an indicator that an eruption will occur, while the increase in the release of SO2 occurs after the eruption of Merapi. Currently, studies on the detection of volcanic gases are still using the in-situ technique where the gas will be taken directly at the source and then analyzed in the laboratory. This is of course very dangerous for the safety of the monitor and also the durability of the tool because the contact system is reactive and corrosive. This study developed a non-contact CO2 and SO2 gas detection system using an infrared camera. The infrared camera produces optical imaging with the unique characteristics of both CO2 and SO2 gases. A new challenge in gas detection using optical imaging is when CO2 and SO2 are mixed. However, it was re-reported in this study that mixed gas optical imaging produces certain unique patterns as an indication of gas detection with a non-contact system designed to detect gas in single gas or mixed gas.
