Abstract

CONVERTISSEUR PERMETTANT LA MISE EN MEMOIRE INTERMEDIAIRE DES ADRESSES DE BALAYAGE ET DES INFORMATIONS VIDEO A L'AIDE DE 5 BITS D'INFORMATION. LA TRAJECTOIRE DE PROPAGATION DES IMPULSIONS ULTRASONORES EST DECOMPOSEE EN DEUX VECTEURS ET LE MILIEU DANS LEQUEL SE TROUVE LA TRAJECTOIRE DE PROPAGATION EST DEFINI SOUS FORME D'UNE SUCCESSION DE SEGMENTS CONTINUS QUI SONT AFFICHES DE MANIERE CORRESPONDANTE SOUS FORME D'ELEMENTS D'IMAGE. UNE SERIE DE PREMIERS SIGNAUX INDIQUE LA TRAVERSEE DES LIMITES ENTRE SEGMENTS DANS LA DIRECTION DU VECTEUR DANS LAQUELLE CETTE TRAVERSEE EST LA PLUS RAPIDE. UN SECOND SIGNAL PRODUIT ET AYANT UNE VALEUR UNIQUE INDIQUE QUE L'IMPULSION TRAVERSE CES LIMITES DANS LA DIRECTION DE L'AUTRE VECTEUR. APPLICATION A LA REPRODUCTION VISUELLE DES REFLEXIONS D'IMPULSIONS ULTRASONORES INJECTEES DANS UN CORPS ET PROVENANT DE DISCONTINUITES.
