The absolute weight measurement device according to atomic interferometry geophysical applications oriented to monitor the accumulation of hydrocarbons, especially

摘要

Continuously arranged downward along the vertical direction (14), seismic damping system retroreflective mirror (21) and (15) (16), ultra-vacuum system supporting surface (13), a laser system (13) laser system absolute weight measurement device including a state of being a (10), seismic damping system (15), and a (1002) top plate with 1003 holes, retroreflective mirror (21), at least three It will remain suspended above the hole (1003) by (70, 71) metallic blades, metal blades 3 (70, 71) has been bound around the upper plate (1002) and a second end which is positioned above the hole (1003) corresponds to (21) retroreflective mirror and a first end, a metal blade (70, 71) is, along a vertical direction spring damping vibrations retroreflective mirror (21) - is configured to form an anti-spring geometry, in the apparatus, the absolute weight measurement device (10), integral (15) seismic damping system means for adjusting the horizontal (21) retroreflective mirror, be provided between the retroreflective mirror (21) the upper plate (1002), radial constraint acting in a plane which is perpendicular to the vertical direction there and means, devices.
