Abstract
L'invention concerne un dispositif pour la transmission optique d'informations. Dans l'appareil de télévision 1 sont montées deux diodes d'émission 2, 3 pour la transmission des canaux stéréo reçus par un écouteur porté par la tête d'une personne 4 et comportant des corps fluorescents 8, 9 captant la lumière et contenant une substance fluorescente et étant muni d'une fenêtre de sortie de la lumière, la bande d'absorption de la substance fluorescente coïncidant au moins approximativement avec la bande d'émission de l'émetteur de lumière 2, 3 et ne recouvrant pratiquement pas la bande d'émission de ladite substance fluorescente. Application notamment à la transmission de signaux sur de courtes distances dans des espaces fermés notamment pour la transmission d'images et de sons.
