Abstract

PROCEDE CONSISTANT A MESURER LA VARIATION DE DISTANCE ENTRE LA SURFACE DE LA BANDE ET UN CAPTEUR DEVANT LEQUEL ELLE DEFILE, EN ELIMINANT LA VARIATION PARASITE DE LA DISTANCE, DUE A LA VIBRATION PROPRE DE LA BANDE TENDUE ENTRE DEUX ROULEAUX SUPPORTS. LA BANDE SUBIT UN MOUVEMENT DE TRANSLATION EN PASSANT SUR DEUX ROULEAUX CYLINDRIQUES PARALLELES 4 ET 5. ELLE EST SOUMISE NATURELLEMENT A UNE VIBRATION PROPRE MATERIALISEE PAR LA LIGNE A, LA VARIATION DE DISTANCE DUE AUX SEULS DEFAUTS DE PLANEITE ETANT REPRESENTEE PAR LA COURBE L. LA COMPOSANTE A EST ELIMINEE ET LA HAUTEUR RELATIVE DES DEFAUTS EST PROPORTIONNELLE AU RAPPORT ENTRE H (AMPLITUDE) ET L (LONGUEUR D'ONDE).
