Title:
特に炭化水素の貯留をモニタするための地球物理学的用途向きの原子干渉法による絶対的重量測定装置
Document Type and Number:
Japanese Patent JP2014504720
Kind Code:
A
Abstract:
An absolute gravimetric measurement device including, in succession, a laser system, a supporting surface of the laser system, an ultra-vacuum system, a retroreflective mirror, and a seismic attenuation system. The seismic attenuation system includes an upper plate including a hole above which the retroreflective mirror is kept suspended by at least three metallic blades including first ends constrained to a periphery of the plate and second ends above the hole in correspondence with the retroreflective mirror, the metallic blades configured to form a spring-antispring geometry for damping vibrations of the retroreflective mirror. The absolute gravimetric measurement device also includes a mechanism leveling the retroreflective mirror integral with the seismic attenuation system and a radial constraining mechanism between the retroreflective mirror and the upper plate.
