Abstract

DISPOSITIF POUR L'OBSERVATION A DISTANCE DES OBJETS DANS LES CHAMPS DE RAYONNEMENTS IONISANTS. LE DISPOSITIF SUIVANT L'INVENTION EST UN CANAL DE FIBRES OPTIQUES POUR LA TRANSMISSION DE L'IMAGE DE L'OBJET OBSERVE 2 AU-DELA DES LIMITES DE LA PROTECTION BIOLOGIQUE. LE CANAL DE FIBRES OPTIQUES COMPORTE UN OBJECTIF D'ENTREE 1 QUI PROJETTE L'IMAGE DE L'OBJET 2 SUR LA FACE D'ENTREE DU FAISCEAU DE FIBRES OPTIQUES 3 DONT L'EXTREMIE DE SORTIE EST DISPOSEE EN DEHORS DE LA PROTECTION BIOLOGIQUE. LE CANAL COMPORTE EGALEMENT UNE SOURCE DE CHALEUR POUR LE MAINTIEN AU MOINS DU FAISCEAU DE FIBRES OPTIQUES 3 A UNE TEMPERATURE ASSURANT LA THERMOSTABILISATION DE SA TRANSMISSION DE LA LUMIERE SOUS L'ACTION D'UN RAYONNEMENT IONISANT 9. LE DISPOSITIF EST DESTINE A ETRE UTILISE ESSENTIELLEMENT DANS DES UNITES NUCLEAIRES POUR LA PRODUCTION DE L'ENERGIE.
