GRAVITATIONAL GRADIOMETER |
摘要 |
Apparatus for the measurement of quasi-static gravity gradients comprising: a flexible ribbon held under tension at both ends; sensing means arranged to detect the transverse displacement of the ribbon from an undisturbed position due to the gravitational field acting on said ribbon and to generate a signal representing the displacement; and output means coupled to said sensing means and responsive to said displacement signal to generate an output signal which is a function of the gravitational gradient tensor of the gravitational field; wherein the ribbon has a non-uniform rigidity profile and/or mass profile along its length such that, in use, the displacement response of the ribbon due to the gravitational gradient of the gravitational field is enhanced and/or the displacement response of the ribbon due to the absolute gravitational acceleration of the gravitational field is suppressed. |
