Abstract
Sonde à fibres optiques permettant de détecter la présence ou l'absence d'une ou de plusieurs substances dans un milieu. La sonde comprend au moins une fibre optique éclairante servant à guider la lumière d'excitation à partir d'une source de lumière conçue pour être dirigée vers une extrémité de la fibre optique éclairante. Un film ou un milieu d'immersion est prévu pour émettre de la lumière lorsqu'illuminé par la lumière d'excitation. La lumière émise présente une longueur d'onde centrale qui est différente d'une longueur d'onde centrale de la lumière d'excitation. Au moins une fibre optique de réception est prévue pour recevoir et guider la lumière émise. La fibre de réception peut être une fibre en cristal photonique dotée d'une partie terminale faite d'un segment de verre solide, pour permettre une meilleure efficacité en matière de captage de lumière. Une lentille peut se trouver à l'extrémité de la fibre de réception. Des éléments de détection sont prévus pour détecter la lumière à partir de la fibre optique de réception.
