A method and system for normalizing optical spectra using a non-uniform segment normalization. A spectrum is obtained and is represented as a function of wavelength as an amplitude at each of a plurality of wavelengths. At least one segment of the spectrum is selected, each selected segment being bounded by an upper wavelength and a lower wavelength. A normalization factor is computed as the sum of the areas for each of the selected segments. The spectrum is normalized by dividing at least one amplitude of the spectrum by the normalization factor. Segments can be selected with different wavelength ranges, that is, segments can be non-uniform. Test specimens can be categorized based on an analysis of normalized spectra. In particular, the specimen to be tested can be human cervical tissue, and the state of health of the tissue can be determined.

L'invention concerne un procédé et un système permettant de normaliser des spectres optiques par normalisation de segment non uniforme. Un spectre est obtenu et représenté en fonction de longueur d'onde en tant qu'amplitude à chacune d'une pluralité de longueurs d'onde. On choisit au moins un segment du spectre, lequel segment est délimité par une longueur d'onde supérieure et une longueur d'onde inférieure. On calcule un facteur de normalisation comme somme des surfaces pour chacun des segments choisis. On normalise le spectre en divisant au moins une amplitude de ce spectre par le facteur de normalisation. Les spectres peuvent être choisis avec différentes gammes de longueurs d'onde, c'est-à-dire, les segments peuvent être non uniformes. On peut catégoriser des spécimen d'essai sur la base d'une analyse des spectres normalisés. En particulier, le spécimen d'essai peut être du tissu cervical humain et on peut en déterminer l'état de santé.
