Abstract
UN FAIBLE VOILE SE PRODUISANT AUTOUR DU SPOT SUR L'ECRAN IMAGE AUX ANGLES DE LA PERIPHERIE DE L'ECRAN ROUGE S'OBTIENT LORSQUE LA PREMIERE GRILLE FORME, EN COOPERATION AVEC LA CATHODE, UNE LENTILLE ESSENTIELLEMENT QUADRIPOLAIRE, ET EN COOPERATION AVEC LA SECONDE GRILLE EGALEMENT, UNE "SECONDE" LENTILLE QUADRIPOLAIRE LAQUELLE EST TOURNEE DE 90 PAR RAPPORT A LA PREMIERE LENTILLE QUADRIPOLAIRE. UN TEL SYSTEME DE LENTILLES DANS LA PREMIERE GRILLE SE FORME PAR EXEMPLE LORSQUE L'OUVERTURE DE LA PREMIERE GRILLE, PRESENTE UNE SECTION OBLONGUE, TANT DU COTE CATHODIQUE QUE DU COTE DE LA SECONDE GRILLE, LE GRAND AXE DU COTE CATHODIQUE ETANT PRATIQUEMENT PERPENDICULAIRE AU GRAND AXE DU COTE DE LA SECONDE GRILLE. APPLICATION: TUBE IMAGE DE TELEVISION.
