GRAVITY METER Russian patent published in 2005 - IPC

FIELD: gravity meter is used at carrying out high-precision measuring of gravity force and its increase.

SUBSTANCE: gravity meter has a body with distributed in it an elastic element and explorative mass, an arrangement of registration of displacement of explorative mass and a system of processing results. The arrangement of displacement of explorative mass is executed in the form of a laser measuring instrument of displacement with reversing calculation of interference fringes. At that the elastic element has at least two flat springs. The heterodyne laser measuring instrument of displacement with reversing calculation of interference fringes has corner reflectors. The height of the corner reflectors may be located at least in one of the vertical surfaces of symmetry of the elastic element.

EFFECT: increases precision and stability of measuring results and increases operating speed of the gravity meter's work.
