Title (EN) SIDE-FIRING OPTIC FIBER TIP WITH LENGTH-BASED BEAM DIAMETER
(FR) POINTE DE FIBRE OPTIQUE À ÉMISSION LATÉRALE AVEC DIAMÈTRE DE FAISCEAU BASÉ SUR LA LONGUEUR
Abstract:
(EN) An optic fiber (204, 304) having a core (208, 308) and a cladding (210, 310) surrounding the core. The core is coupled to a coreless rod (202, 302). The coreless rod has a free end defining a total internal reflection surface(216, 316). The coreless rod has a diameter (218, 318) that is greater than the diameter (220, 320)of the core. As light passes along the coreless rod, the diameter of the light increases. The light reflects off the total internal reflection surface of the coreless rod and exits through a side of the coreless rod.
(FR) L'invention porte sur une fibre optique (204, 304) comportant une âme (208, 308) et une gaine (210, 310) entourant l'âme. L'âme est couplée à une tige sans âme (202, 302). La tige sans âme possède une extrémité libre définissant une surface de réflexion interne totale (216, 316). La tige sans âme a un diamètre (218, 318) qui est supérieur au diamètre (220, 320) de l'âme. À mesure que la lumière passe le long de la tige sans âme, le diamètre de la lumière augmente. La lumière se réfléchit hors de la surface de réflexion interne totale de la tige sans âme et sort à travers un côté de la tige sans âme.
