Patent

CA 2356623

The present invention relates to systems and methods for examining a sample using a substantially monostatic, substantially confocal optical system comprising transmitting optics that focus an illuminating Light upon the sample and receiving optics that collect light emitted from the sample following illumination thereof. In certain embodiments, the receiving optics may be arranged circumferentially around the light path traversed by the illuminating light. In certain embodiments, video apparatus may be included to produce images or to align the system in proximity to the target tissue. The systems and methods of the present invention may be directed towards the examination of a body tissue to provide a medical diagnosis.

Cette invention concerne des systèmes et des procédés d'analyse d'un échantillon. On utilise un système optique essentiellement monostatique et essentiellement confocal comprenant des optiques d'émission destinées à focaliser une lumière d'illumination sur un échantillon ainsi que des optiques de réception destinées à capter la lumière émise par l'échantillon après l'illumination de ce dernier. Selon certains modes de réalisation, on peut placer les optiques de réception de manière circonférentielle autour de la trajectoire suivie par la lumière d'illumination. Selon certains modes de réalisation, on peut ajouter au système un appareil vidéo destiné à produire des images ou à aligner le système au voisinage du tissu-cible. Les systèmes et procédés décrits par la présente invention peuvent être utilisés pour l'analyse d'un tissu organique afin d'établir un diagnostic médical.
