Abstract

L'invention concerne la mesure des gradients de gravité. Un dispositif de mesure de gradient de gravité comprend essentiellement une cavité de laser en anneau formée par les miroirs 4, 6, 8 et 10, dans laquelle se propage un faisceau laser. Le faiseau 3 traverse un élément modulateur 12 qui est constitué par un barreau de quartz dont les deux extremités portent des dipôles de masse 16 et 18. Un détecteur 30 détecte la fréquence de battements que le mouvement des dipôles sous l'effet des gradients de gravité fait apparaître dans le faisceau laser 3. Application à la mesure de gradients de gravité dans les son ages.
