Abstract

Cette invention concerne l'introduction, dans un dispositif à fibre optique de système d'alarme et de surveillance, d'un diviseur de fibres optiques (7) et d'un réflecteur (11) afin d'accroître la sensibilité et les probabilités de détection d'un intrus. La sortie de la source (1) de rayonnement cohérent est connectée au premier accès (8) du diviseur de fibres optiques (7) dont le second accès (9) est relié à la première connexion d'un câble optique à modes multiples (2). La seconde connexion de ce même câble est quant à elle reliée au miroir du réflecteur (11), tandis que le troisième accès (10) est relié à l'entrée d'un appareil photodétecteur (3).
