How does thermal camera for gas leak detection works?
--------------------------------------------------------------------------------------------
If a thermal camera reads a scene without gas leak, objects in the angle of view will radiate and reflect infra-red radiation that will react through the lens and the filter on the detector. The filter only lets some wave lengths of radiation enter the detector from which the camera generates not compensated image of radiation intensity of the radiation (then we speak about the apparent temperature).
If there is a cloud of gas between the lens and thermal camera, this gas will selectively absorb radiation to the extent of its spectral absorption and the amount of radiation passing through the gas which affects the detector will be lower. The principle is explained in detail in this article: Using thermal cameras to visualize gas leaks.
