Abstract

Urządzenie do pomiaru drgań, zwłaszcza sejsmicznych zawierające układ podstawy (1) oraz bezwładną masę (2), które zawiera ramiona pomiarowe (4) i referencyjne (3) interferometru światłowodowego przymocowane do układu podstawy (1) i bezwładnej masy (2), tak, że ramię referencyjne (3) zamocowane jest trwale i nierozłącznie do podstawy (1) a ramię pomiarowe (4) zamocowane jest do bezwładnej masy (2) tak, że co najmniej część ramienia pomiarowego (4) jest unieruchomiona na powierzchni albo w strukturze bezwładnej masy. Sposób pomiaru drgań, zwłaszcza sejsmicznych w jakim zestawione ze sobą podstawę (1) oraz bezwładną masę (2), do jakich zamocowane są ramiona co najmniej jednego interferometru światłowodowego, którego ramię referencyjne (3) zamocowane jest trwale i nierozłącznie do podstawy (1), a ramię pomiarowe (4) zamocowane jest do bezwładnej masy (2) i posiada co najmniej jeden wiotki, ruchomy odcinek, umieszcza się w miejscu, gdzie obserwowane są drgania, w szczególności drgania sejsmiczne, a następnie wprowadza się poprzez co najmniej jeden wejściowy element sprzęgający (5) wiązkę światła.A device for measuring vibrations, especially seismic ones, containing the base system (1) and the inertial mass (2), which includes measuring arms (4) and reference (3) fiber optic interferometer attached to the base system (1) and the inertial mass (2), yes, that the reference arm (3) is permanently and permanently attached to the base (1) and the measuring arm (4) is attached to the inertial mass (2) so that at least part of the measuring arm (4) is fixed on the surface or in the inertial mass structure . The method of measuring vibrations, especially seismic in which the base (1) and the inertial mass (2) are juxtaposed, to which the arms of at least one fiber optic interferometer are attached, whose reference arm (3) is permanently and permanently attached to the base (1), and the measuring arm (4) is attached to the inertial mass (2) and has at least one flaccid, movable section, is placed in a place where vibrations are observed, in particular seismic vibrations, and then introduced through at least one input coupling element (5) light beam.
