Title (EN) MEASUREMENT METHOD OF VIBRATIONS, ESPECIALLY OF SEISMIC TYPE, AND A DEVICE FOR THE MEASUREMENT OF VIBRATIONS, ESPECIALLY OF SEISMIC TYPE
(FR) PROCÉDÉ DE MESURE DE VIBRATIONS, EN PARTICULIER DE TYPE SISMIQUE, ET DISPOSITIF DE MESURE DE VIBRATIONS, EN PARTICULIER DE TYPE SISMIQUE
Abstract:
(EN) The device for measuring vibrations, particularly seismic ones, incorporating a base assembly (1) and the inert mass (2), which contains measuring arms (4) and a reference interferometer (3) attached to the base assembly (1) and the inert mass (2), so that the reference arm (3) is permanently and indissociably fixed to the base assembly (1) and the measuring arm (4) is attached to the inert mass (2) in such a way that at least a part of the measuring arm (4) is immobilised on the surface of or in the structure of the inert mass. The method of measuring vibrations, especially seismic ones, including the base (1) and the inert mass (2), to which the arms of at least one fibre-optic interferometer are attached, the reference arm (3) of which is permanently and indissociably fixed to the base (1), and the measuring arm (4) is fixed to the inert mass (2) and has at least one frail, movable section and which is placed in the location where vibrations, especially seismic ones, are observed, after which a light beam is introduced through at least one input coupling element, which is distributed in at least one input coupling element (5).
(FR) La présente invention concerne un dispositif de mesure de vibrations, en particulier de type sismique, comprenant un ensemble base (1) et une masse inerte (2), contenant des bras de mesure (4) et un interféromètre de référence (3) fixés à l'ensemble base (1) et à la masse inerte (2), de sorte que le bras de référence (3) est fixé de manière permanente et indissociable à l'ensemble base (1) et le bras de mesure (4) est fixé à la masse inerte (2) de telle sorte qu'au moins une partie du bras de mesure (4) est immobilisée sur la surface de la structure de la masse inerte ou à l'intérieur de celle-ci. Le procédé de mesure de vibrations, en particulier des vibrations sismiques, comprend la base (1) et la masse inerte (2), auxquelles sont fixés les bras d'au moins un interféromètre à fibre optique, dont le bras de référence (3) est fixé de manière permanente et indissociable à la base (1), et le bras de mesure (4) est fixé à la masse inerte (2) et comporte au moins une partie mobile fragile et qui est placée dans l'emplacement où des vibrations, en particulier des vibrations sismiques, sont observées; après quoi un faisceau lumineux est introduit à travers au moins un élément d'accouplement d'entrée, qui est réparti dans au moins un élément d'accouplement d'entrée (5).
