PROCESS CONTROL SYSTEM FOR LASER DEVICES for absolute gravity measurements by atomic interferometry for geophysical applications, in particular for hydrocarbon deposits CONTROL

摘要

1. A method (100) of the laser device management system for absolute measurement of gravity by atomic interferometry for geophysical applications, comprising: forming (101) for cooling beams, capturing, manipulation and pushing the plurality of detection atoms by running two sources (23, 24); - cooling (102) said plurality of atoms by activating and entering into the cooling cell counter propagating beams to create a two-dimensional magneto-optical trap (53), - capturing (103) the set of said and cooled atoms in a three-dimensional magneto-optical trap by means of activation and input beams for creating a three-dimensional magneto-optical trap (32) in the primary chamber (61) ultravakuumnoy system (14) simultaneously with the generation of the magnetic field of the trap - deflation (104) of said plurality of atoms from the trap into the free ultravakuumnoy drop in said system (14), - execution (107) by activating interferometric procedures Raman interferometric beams (41) superimposed on each other, during free fall tions of said plurality of atoms; u execution (108) by detecting the activation beams (31) detecting, characterized in that said step (104) discharging into a free fall of the set of atoms includes a step which consists in switching off (109) said three dimensional magneto-optical trap by the simultaneous turning off of said beams for forming a three-dimensional magneto-optical trap (32) and the magnetic field lovushki.2. The method (100) according to claim 1, characterized in that said step of venting (104) said plurality of atoms in freedoms
