Abstract

Dispositif (100) pour quantifier un changement dans des conditions environnementales le long de la longueur d'une fibre optique (130) comprenant un générateur d'impulsions optiques à balayage de fréquence (110) pour générer des séquences d'impulsions d'impulsions optiques ; un composant optique (120) couplé au générateur d'impulsions (110) pour injecter les impulsions optiques dans une fibre optique (130) et pour rediriger le signal optique rétrodiffusé à partir de la fibre optique (130) ; et un module récepteur (150) couplé au composant optique (120). Le module récepteur (150) comprend un interféromètre (170) pour déterminer des informations de phase du signal optique rétrodiffusé en fonction du temps et de la fréquence optique.
