(57) Abstract :
The present invention relates to a method (20) for detecting N gases, each having a corresponding spectral signature. The method (20)
comprises determining (201), on the basis of a Principal-Component Analysis of the spectral signatures of the N gases, M
wavelengths, on the basis of which said spectral signatures can be represented. Furthermore, the method (20) comprises emitting
(202), for each of the M wavelengths determined, a corresponding electromagnetic radiation having said wavelength. The method (20)
also comprises acquiring (203) , for each of the M wavelengths determined, a corresponding back-scattered electromagnetic radiation
having said wavelength. Finally, the method (20) comprises detecting and identifying (204) one of the N gases on the basis of the
corresponding spectral signature and of at least one electromagnetic radiation acquired.
