Abstract

La présente invention concerne un système d'endoscope à longueurs d'onde multiples destiné à photographier un site d'observation marqué avec une pluralité de matériaux fluorescents de couleurs différentes, le système comprenant : une unité de photographie destinée à polariser la lumière incidente réfléchie au niveau du site d'observation dans une première direction et une seconde direction perpendiculaire à la première direction, à diviser une région spectrale de la lumière incidente polarisée dans la première direction et la seconde direction en une pluralité de canaux spectraux, et à mesurer l'intensité lumineuse de chaque canal spectral parmi la pluralité de canaux spectraux en vue d'obtenir des données d'image ; et une unité informatique destinée à stocker un spectre de fluorescence unique extrait de données d'image d'échantillon photographiées par traitement unique du site d'observation avec chacun des matériaux fluorescents, et à séparer et à délivrer en sortie les données d'image photographiées par l'unité de photographie à l'aide du spectre de fluorescence unique de telle sorte que seulement un matériau fluorescent parmi la pluralité de matériaux fluorescents est affiché.
