Abstract
L'INVENTION CONCERNE UN DISPOSITIF DESTINE A DETERMINER UNE POSITION SUR UN ELEMENT A RETARD. CE DISPOSITIF COMPORTE UN TRANSDUCTEUR DE COMMANDE DESTINE A ENGENDRER UNE ONDE PROGRESSIVE DANS L'ELEMENT A RETARD. CETTE ONDE EST DETECTEE PAR UN TRANSDUCTEUR DE RECEPTION DE MANIERE A PERMETTRE UNE DETERMINATION DES POSITIONS RELATIVES DES DEUX TRANSDUCTEURS. LE TRANSDUCTEUR DE COMMANDE, L'ELEMENT A RETARD ET LE SECOND TRANSDUCTEUR FORMENT UN OSCILLATEUR A BOUCLE DE REACTION ET AUTO-EXCITATION DONT LA FREQUENCE D'OSCILLATION DEPEND DU FILTRAGE REALISE PAR LE SECOND TRANSDUCTEUR. DOMAINE D'APPLICATION: DETERMINATION D'UNE POSITION SUR UN ELEMENT A RETARD DE FORME LINEAIRE OU PLANE.
