- Abstract:
- In this paper, passive thermography is proposed as a non-contact method to detect leakages or production of harmful and polluting gases. This technique can be used for a wide range of applications concerning the environmental monitoring. Infrared imaging allows to detect in real-time harmful and invisible gases such as methane, sulphur hexafluoride, ethylene, ammonia, carbon monoxide so to prevent hazards or explosions. By a spectral analysis of the heat radiation of the target into the infrared spectrum range, it is possible to characterize the presence of specific gasses or volatile compounds. In detail, spectral filters allow thermal infrared cameras to detect gas molecules radiating or absorbing radiation in a narrow infrared range. According to the spectral range of the gas, it is possible to build an appropriate selecting filter.
