GRADIOMETER CONFIGURATION INVARIANT TO LASER PHASE NOISE AND SENSOR ROTATIONS |
| 摘要 |
A system for gravity measurement includes one or more atom sources, two or more laser beams, and a polarizing beamsplitter and a retro-reflection prism assembly. The one or more atom sources is to provide three ensembles of atoms. The two or more laser beams is to cool or interrogate the three ensembles of atoms. The polarizing beamsplitter and the retro-reflection prism assembly are in a racetrack configuration. The racetrack configuration routes the two or more laser beams in opposing directions around a loop topology, intersecting the three ensembles of atoms with appropriate polarizations chosen for cooling or interferometer interrogation. The three ensembles of atoms are positioned coaxially when interrogated. |

1. A system for gravity measurement comprising:
one or more atom sources to provide three ensembles of atoms; two or more laser beams to cool or interrogate the three ensembles of atoms; and s a polarizing beamsplitter and a retro-reflection prism assembly in a racetrack configuration, wherein the racetrack configuration routes the two or more laser beams in opposing directions around a loop topology, intersecting the three ensembles of atoms with appropriate polarizations chosen for cooling or interferometer interrogation, wherein the three ensembles of atoms are positioned coaxially when interrogated. |
