Patent abstract
A system for measuring differential gravity at two points is disclosed. In the illustrative embodiment, the system uses a pair of graspers which each repeatedly grasp, raise, and drop a test mass. The accelerations of the two free-falling test masses are monitored using optical interferometry. An output signal is provided that is based on a differential acceleration of the two test masses.
