摘要： A low-temperature superconducting device for measuring gravity, includes a low-temperature container, a cryocooler, a rotor chamber, a superconducting rotor, an upper levitation coil, a lower levitation coil, an upper electrode, an intermediate electrode, a lower electrode, a magnetic shielding chamber and a superconducting quantum interference device. By cooling the whole low-temperature superconducting device using a cryocooler, the intermediate electrode disposed in the body of the magnetic shielding chamber will generate an output voltage when the superconducting rotor is displaced due to a change of gravity. Thus, the superconducting quantum interference device can make the superconducting rotor return to the central balance position by adjusting the operating current of the upper levitation coil or the lower levitation coil. A change of gravity can be determined based on the operating current fed back to the upper levitation coil or the lower levitation coil.

摘要： The present disclosure provides a gravity gradiometer for detecting a gravity gradient. The gravity gradiometer comprises at least two sensor masses that are pivotable about respective axes and each experience a change in torque in response to a change in gravity gradient whereby the at least two sensor masses move relative to each other in response to the change in gravity gradient and wherein a signal indicative of the gravity gradient is generated in response to the relative movement of the at least two sensor masses. Further, the gravity gradiometer comprises an acceleration sensor for sensing an acceleration associated with an external acceleration applied to the gravity gradiometer. The gravity gradiometer also comprises an actuator for generating an adjustment force that is dependent on an acceleration sensed by the acceleration sensor. The adjustment force is also dependent on a mechanical response parameter associated with at least one of the at least two sensor masses. The adjustment force is applied such that a difference between the magnitudes of the torques experienced by the at least two sensor masses in response to the change in gravity gradient is reduced.
