OPTICAL SENSOR OF CHEMICAL SPECIES OPERATING IN INFRARED |
abstract |
An optical sensor for chemical species comprising: - a fluorescent source of incoherent infrared radiation (3), comprising a chalcogenide glass matrix doped with rare earth ions; at least one infrared radiation detector (5) provided with a spectral selection device (50) and arranged to detect the radiation emitted by said fluorescent source, a detection zone (6) of chemical species being provided between said source and said detector; and a pumping source (1) emitting visible or infrared radiation adapted to excite the fluorescence of said rare earth ions. A method for detecting a chemical species by measuring the absorption, at at least two distinct wavelengths (λλ), of the incoherent infrared radiation emitted by fluorescence by rare earth ions in a chalcogenide glass matrix ( 3). |
