Abstract

L'INVENTION CONCERNE UN DISPOSITIF TRADUCTEUR COURANT-LUMIERE APPLIQUE EN CATHODOLUMINESCENCE, PERMETTANT UNE SELECTION ET UN MELANGE COLOROMETRIQUE. ASSOCIANT LES EFFETS PHYSIQUES DE L'ELECTROLUMINESCENCE DES SOLIDES, DE LA CATHODOLUMINESCENCE ET DE LA COLOROMETRIE, TROIS CONDENSATEURS ELECTROLUMINESCENTS SUPERPOSES (EMETTANT RESPECTIVEMENT DES LUMIERES ROUGES, BLEUES, VERTES) CONSTITUENT LA FACE AVANT D'UN TUBE IMAGE MONOCANON. SOUS L'EFFET DU BOMBARDEMENT CATHODIQUE, AU POINT D'IMPACT DU SPOT, UN POINT LUMINEUX APPARAIT. SIMULTANEMENT, UN RENFORCEMENT LOCAL DE BRILLANCE DU POINT IRRADIE, DANS LA COULEUR DESIREE, EST OBTENU EN APPLIQUANT UNE TENSION DETERMINEE AU CONDENSATEUR CORRESPONDANT. CE RESULTAT, SEUL VISIBLE DONNE UN PARAMETRE DE COMMANDE POUR LA SELECTION ET LE MELANGE EVENTUEL DES CHROMINANCES. L'OEIL N'AYANT AUCUNE SYNTHESE A EFFECTUER LA SUCCESSION DES POINTS LUMINEUX (SANS EFFET SECONDAIRE) DANS LEURS BRILLANCES ET LEURS COULEURS EXACTES DONNE UNE RESTITUTION PARFAITE DES TEINTES ET DES NUANCES.
