| 摘要 |
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. |
