Abstract[English]
In certain embodiments, an optical system for obtaining surgical information includes a probe housing a first optical fiber, a light source, a photoanalyzer, and an optical circulator optically coupled to each of the first optical fiber, the light source, and the photoanalyzer. The optical circulator has a first port configured to receive source light generated from the light source, a second port configured to transmit the source light from the first port to the first optical fiber, and a third port configured to transmit return light in the first optical fiber from the second port to the photoanalyzer. The first optical fiber is configured to emit at least a portion of the source light in the first optical fiber from the probe to contact a body structure, and collect light returning from the body structure as a result of the portion of the source light contacting the body structure.[French]
L'invention concerne, selon certains modes de réalisation, un système optique pour obtenir des informations chirurgicales comprenant une sonde logeant une première fibre optique, une source de lumière, un photoanalyseur et un circulateur optique couplé optiquement à la première fibre optique, à la source de lumière et au photoanalyseur. Le circulateur optique possède un premier port configuré pour recevoir la lumière source générée par la source lumineuse, un deuxième port configuré pour transmettre la lumière source du premier port à la première fibre optique, et un troisième port configuré pour transmettre la lumière de retour dans la première fibre optique du deuxième port au photoanalyseur. La première fibre optique est configurée pour émettre au moins une partie de la lumière source dans la première fibre optique à partir de la sonde pour entrer en contact avec une structure corporelle, et recueillir la lumière renvoyée par la structure corporelle à la suite de l'entrée en contact de la partie de la lumière source avec la structure corporelle.
