Abstract
L'invention se rapporte aux systèmes de repérage d'une pointe posée sur un plateau. L'invention a pour objet un système de repérage fonctionnant selon le principe de la localisation par ondes élastiques de surface et dans lequel le plateau de mesure est confectionné à partir de lamelles cristallines. L'invention s'applique notamment au traitement par ordinateur des signes graphiques sur un tableau.
