Abstract

SYSTEME DE MESURE DES RESEAUX PASSIFS DE CAPTEURS DE FIBRE OPTIQUE Le système permet de mesurer des réseaux de capteurs de fibre optique sur des réseaux optiques passifs, en utilisant des lasers syntonisables à semi-conducteur travaillant en régime d'onde continue. Concrètement le laser sintonisable (2), muni de son contrôleur correspondant (3) et via un circulateur (4), envoie des signaux d'une longueur d'onde déterminée au réseau passif (1) de capteurs optiques durant une période de temps T1, suite à laquelle la longueur d'onde change et les signaux réfléchis sont reçus dans le réseau de capteurs dans un convertisseur électro-optique (6), de préférence via un filtre (5) à bande éliminée, qui rejette la bande "off". Figure 1.-SYSTEM FOR MEASURING PASSIVE NETWORKS OF FIBER OPTIC SENSORS The system makes it possible to measure networks of fiber optic sensors on passive optical networks, using tunable semiconductor lasers working in continuous wave regime. Concretely the sintonisable laser (2), provided with its corresponding controller (3) and via a circulator (4), sends signals of a determined wavelength to the passive network (1) of optical sensors during a period of time T1 , as a result of which the wavelength changes and the reflected signals are received in the sensor network in an electro-optical converter (6), preferably via a filter (5) with eliminated band, which rejects the band "off" .
