A stereoscopic measuring device for determining position information of an event location comprises a background surface and a lighting assembly having a first lighting position and a second lighting position for the illumination of the background surface at different angles. The light beams from the lighting positions passing through an event location are projected at spaced-apart projection locations at a projection location distance. The measuring device also includes an imaging apparatus for imaging the projection locations and an evaluation apparatus for detecting an event, for determining the projection location distance and the position information of the event location based on the projection location distance. The event location is a location at which the medium to be detected appears. Its interaction with the light beams changes a property of the projection locations compared to reference conditions in which the medium to be detected is absent or effective in a different way.

Stereoscopic measuring device for determining position information of an event location in an interstitial space from a reference point and method for determining position information of an event location in an interstitial space

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.
