Abstract
a. Détecteur optique de fumée du type dans lequel la présence de fumée modifie la réception par un transducteur de la lumière d'une source lumineuse, pour déclencher une alarme. b. Détecteur caractérisé par un dispositif pour polariser optiquement le transducteur, comprenant des moyens pour déterminer le champ de vision de ce transducteur et des moyens pour contraindre une quantité contrôlée de lumière de la source à atteindre le champ de vue du transducteur. c. Détecteur applicable à la détection préalable de débuts d'incendie.
