Abstract: A detector device for optically detecting a gas in a zone of space under observation, the device comprising a camera and means for continuously detecting at least one gas in the observed zone by analyzing absorbance in a plurality of different spectral bands. The device further comprises a matrix of micromirrors that are individually steerable between at least two positions, in a first of which they reflect the radiant flux coming from the observed zone to the camera for detecting gas in said spectral bands, and in a second of which they reflect the radiant flux coming from the observed zone to a Fourier transform infrared spectroscope.
