Multiaxis Inertial Sensing with Long-Time Point Source Atom Interferometry
Multiaxis Inertial Sensing with Long-Time Point Source Atom Interferometry
We show that light-pulse atom interferometry with atomic point sources and spatially resolved detection enables multi-axis (two rotation, one acceleration) precision inertial sensing at long interrogation times. Using this method, we demonstrate a light-pulse atom interferometer for Rb-87 with 1.4 cm peak wavepacket separation and a duration of 2T = …
