Abstract

L'invention concerne les mesures optiques. Dans un cathéter à fibres optiques de transmission et de réception, pour analyse photométrique d'un fluide, on élimine la nécessite de calibrer individuellement chaque cathéter d'un ensemble de cathéters en rendant identiques : les distances centre à centre entre ouvertures de sortie des fibres de transmission et ouvertures d'entrée des fibres de réception d'un cathéter, pour tous les cathéters de l'ensemble ; la forme et les dimensions des ouvertures de sortie des fibres de transmission ainsi que celles des fibres de réception; les orientations des fibres de transmission relativement aux fibres de réception. Application à la mesure de la saturation en oxygène du sang.
