Abstract
(EN) A probe for optically imaging a pathway and associated methods is described. The probe includes a series of optical imaging units that include a beam splitter that rotates about an axis. The beam splitter directs a first portion of sensing light traversing a light path out from the probe in a radial direction onto a wall portion of the pathway and passes a second portion of the sensing light towards an adjacent optical imaging unit of the probe. Returned light from the wall portion of the pathway is received and directed back along the light path.
(FR) L'invention concerne une sonde destinée à l'imagerie optique d'une voie et des procédés associés. La sonde comprend une série d'unités d'imagerie optique qui comprennent un diviseur de faisceau qui tourne autour d'un axe. Le diviseur de faisceau dirige une première partie de lumière de détection traversant un trajet de lumière à l'extérieur de la sonde dans une direction radiale sur une partie de paroi de la voie et fait passer une seconde partie de la lumière de détection vers une unité d'imagerie optique adjacente de la sonde. La lumière renvoyée par la partie de paroi de la voie est reçue et renvoyée le long du trajet de lumière.
