Abstract

L'invention se situe dans le domaine de la métrologie. Elle concerne un dispositif et un procédé de mesure, par rapport à une référence fixe de la position d'un plateau circulaire plan, tournant autour de son axe d'un mouvement comportant des déviations aléatoires de faible amplitude, en translation et en inclinaison de son plan, ainsi que du profil exact de ce plateau, axial et radiaL Ce dispositif comprend quatre capteurs comportant chacun un levier articulé en un point fixe à une extrémité et s'appuyant à l'autre extrémité en un point quelconque du bord du plateau par deux touches, l'une sur la surface parallèle au plan du plateau et l'autre sur le flanc parallèle à l'axe du plateau. L'invention peut s'appliquer à la mesure très précise des dimensions d'un objet porté par ce plateau.
