Abstract
A device for detection of a gas or of a multi-component gas mixture comprises: an optical capture unit for capturing a field of view; a first light source configured to emit light having a current wavelength within a first wavelength range, wherein the first light source is arranged such that the light emitted impinges on the field of view; a first optical filter arranged between the optical capture unit and the first light source, wherein the first optical filter enables only those wavelengths of the light in a first filter wavelength range to pass; and a control/evaluation unit configured to determine, based on at least one image recorded by the optical capture unit, the distribution of the gas or the gas mixture in the field of view, the composition of the gas or the gas mixture, and/or a concentration of the components of the gas mixture.
