Abstract

A cold atom gravity gradiometer system includes a laser source that generates a laser beam that propagates along a propagation direction. The system further includes a reflector that reflects a portion of the laser beam and transmits another portion of the laser beam (the transmitted portion). A second reflector spatially separated from the first reflector along the propagation direction reflects the transmitted portion of the laser beam.
