Abstract

La présente invention se rapporte au matériel de mesurage et plus particulièrement aux instruments servant au mesurage sans contact des oscillations mécaniques des machines, mécanismes et structures de bâtiments. Les oscillations d'un générateur d'hyperfréquences (1), modulées en phase [0,π/2], sont émises depuis la sortie d'un modulateur de phase (9) par une antenne de transmission (2) à destination d'un objet à contrôler. Les oscillations réfléchies par ledit objet sont collectées au moyen d'une antenne de réception (3) et envoyées vers une entrée d'un pont à hyperfréquences (6). Les oscillations du générateur (1) sont envoyées vers une autre entrée du pont à hyperfréquences (6); ces oscillations sont utilisées comme signal de référence. Un convertisseur (7) sert à décaler les spectres des signaux émis et réfléchis dans le domaine des fréquences nulles. On enregistre de façon séquentielle des sélections du signal réfléchi, qui provient de la sortie du convertisseur analogique/numérique (4), dans deux tableaux de données qui font partie d'un dispositif de calcul (5).
