Abstract

L'invention concerne un procédé de mesure de dispersion de longueur d'onde destiné à mesurer directement la dispersion de vitesse de groupe d'un élément optique, par exemple une fibre optique. On mesure la dispersion de vitesse de groupe en utilisant un rayonnement lumineux soumis simultanément à une modulation de fréquence optique et à une modulation d'intensité et en utilisant le fait qu'un composant modulé de fréquence optique apparaît sous forme d'une variation de phase du composant modulé en intensité. La dispersion peut donc être mesurée avec une grande précision sans effet de dérive du temps de retard de groupe provoqué par une variation de l'environnement extérieur. La précision et le domaine dynamique ne se détériorent pas même au voisinage d'une dispersion nulle. Puisqu'il est possible de rendre asymétrique la forme d'onde d'un signal modulé en fréquence, on peut reproduire le code d'une valeur de dispersion de longueur d'onde. La dispersion de longueur d'onde peut être soumise à un contrôle en service en utilisant un signal de données numérique en tant que signal modulé en intensité.
