Visualise gas in infrared !
Interesting to ‘see’ how wearing masks avoid the forward projections of droplets. Beyond the COVID aspect, visualising CO2 is useful in industry, particularly in leak testing. This video was acquired with a NoxCam equipped with a spectral filter that reveals CO2. Such setup is often used to make measurements on a particular part of the infrared light spectrum, to focus on where the greatest contrast can be revealed. NoxCam is an option, but when even faintest leaks need to be detected, GasCore is a must have.
