Summary:The present invention relates to a multi-wavelength endoscope system for photographing an observation site marked with a plurality of fluorescent materials having different colors, the system comprising: a photographing unit for polarizing incident light reflected at the observation site in a first direction and a second direction perpendicular to the first direction, dividing a spectral region of the incident light polarized in the first direction and the second direction into a plurality of spectral channels, and measuring light intensity of each of the plurality of spectral channels to obtain image data; and a computing unit for storing a single fluorescence spectrum extracted from sample image data photographed by singly processing the observation site with each of the fluorescent materials, and separating and outputting the image data photographed by the photographing unit by using the single fluorescence spectrum so that only one of the plurality of fluorescent materials is displayed. 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. 본 발명은 서로 다른 색을 갖는 복수 개의 형광 물질로 표지한 관찰 부위를 촬영하는 다중 파장 내시경 시스템으로서, 관찰 부위에서 반사된 입사광을 제 1 방향과 상기 제 1 방향에 수직인 제 2 방향으로 편광시키고, 상기 제 1 방향과 상기 제 2 방향으로 편광된 상기 입사광의 스펙트럼 영역을 복수의 스펙트럼 채널로 구분하고, 상기 복수의 스펙트럼 채널 각각의 빛의 세기를 측정하여 영상 데이터를 획득하는 촬영부와, 상기 관찰 부위를 각각의 상기 형광 물질로 단일 처리하여 촬영한 샘플 영상 데이터로부터 추출된 단일 형광 스펙트럼을 저장하고, 상기 단일 형광 스펙트럼을 이용하여 상기 촬영부에서 촬영된 영상 데이터를 상기 복수 개의 형광 물질 중 하나의 형광 물질 만이 각각 표시되도록 분리하여 출력하는 컴퓨팅부를 포함한다.
