PHASE CONTROL FOR DUAL ATOM INTERFEROMETERS

摘要

A system for controlling a phase measurement in an atom interferometer comprising one or more lasers, a processor, and a memory. The one or more lasers are for providing interrogating beams. A first cloud of atoms and a second cloud of atoms traverse an interrogating region of the atom interferometer in substantially opposite directions. The interrogating beams interact substantially simultaneously with both atoms in the first cloud and atoms in the second cloud. The first cloud of atoms and the second cloud of atoms interact with each of the interrogating beams in a different order. The processor is configured to determine a phase adjustment offset of at least one interrogating beam based at least in part on one or more past interactions of one or more interrogating beams with either the first cloud of atoms or the second cloud of atoms.

1. A system for controlling a phase measurement in an atom interferometer, comprising:
one or more lasers for providing a plurality of sets of interrogating pulses, wherein a first cloud of atoms and a second cloud of atoms traverse an interrogating region of the atom interferometer in substantially opposite directions, wherein one or more of the sets of interrogating pulses of the plurality of the sets of interrogating pulses interact substantially simultaneously with both atoms in the first cloud and atoms in the second cloud, and wherein the first cloud of atoms and the second cloud of atoms interact with one or more sets of interrogating pulses in a different order; and a processor configured to:
determine a phase adjustment offset of at least one set of interrogating pulses of the plurality of sets of interrogating pulses based at least in part on one or more past interactions of one or more sets of interrogating pulses of the plurality of sets of interrogating pulses with either the first cloud of atoms or the second cloud of atoms; and a memory coupled to the processor and configured to provide the processor with instructions.
