Abstract

DISPOSITIF POUR EXAMINER UN OBJET 7 A L'AIDE D'UN RAYONNEMENT PENETRANT DANS CELUI-CI ET EMIS PAR DES SOURCES 3 POUVANT ETRE AMORCEES L'UNE A LA SUITE DE L'AUTRE. CES SOURCES FORMENT UNE SERIE CONTINUE AUTOUR DE L'OBJET 7 ET COOPERENT AVEC UNE SERIE CONTINUE DE DETECTEURS 5 SITUES DANS LE MEME PLAN QUE LES SOURCES. AU COURS D'UN EXAMEN, LES SOURCES DE RAYONNEMENT 3 EMETTENT, L'UNE A LA SUITE DE L'AUTRE, UN FAISCEAU DE RAYONNEMENT IRRADIANT L'OBJET 7 SUIVANT DIFFERENTES DIRECTIONS ET FRAPPANT LES DETECTEURS VOISINS 5. ON PROCEDE A LA MESURE DU RAYONNEMENT QUE LE CORPS A LAISSE PASSER A L'AIDE DE DETECTEURS 5 QUI, VUS DEPUIS LA SOURCE DE RAYONNEMENT EN VOIE DE FONCTIONNEMENT, SONT SITUES DERRIERE L'OBJET 7.
