Abstract
L'INVENTION CONCERNE UNE CIBLE DE PRISE DE VUES. LA PLAQUE SIGNAL 110 QUI RECOUVRE SUR L'UNE DE SES FACES LA CIBLE PROPREMENT DITE 10 EST FRACTIONNEE EN PLUSIEURS PLAQUES SIGNAL ELEMENTAIRES 101, 102, 103..., ELECTRIQUEMENT INDEPENDANTE, AFIN DE REDUIRE LA CAPACITE PARASITE LORS DU PRELEVEMENT DU SIGNAL SUR CETTE PLAQUE. DANS UNE DISPOSITION PREFEREE, CES PLAQUES ELEMENTAIRES SONT ORIENTEES COMME LES LIGNES DU BALAYAGE PAR LE FAISCEAU D'ELECTRONS DE LECTURE. CETTE LECTURE EST FAITE SOIT PAR UN FAISCEAU UNIQUE, SOIT PAR UN CERTAIN NOMBRE DE FAISCEAUX INDEPENDANTS COUVRANT CHACUN UNE PORTION DE LA CIBLE. MEMES APPLICATIONS QUE DANS L'ART ANTERIEUR, PRISE DE VUES EN INFRA-ROUGE NOTAMMENT.
