摘要： A gradiometer utilizing at least three vector magnetometers (11, 12, 13) (preferably SQUIDs) to measure a magnetic field gradient. An average magnetometer (13) (SQUID) is used to cancel background magnetic fields from outputs of the difference magnetometers (11, 12) via a feedback loop (21, 22, 23) provided with a signal from the average magnetometer (13). Similarly, higher order gradiometers can be built using an average magnetometer cube and a plurality of difference magnetometer cubes. The gradiometer would find application in a wide range of fields, such as geology and medecine.

摘要翻译： 利用至少三个矢量磁强计（11,12,13）（优选SQUID）来测量磁场梯度的梯度计。 平均磁力计（13）（SQUID）用于通过设置有来自平均磁力计（13）的信号的反馈回路（21,22,23）来消除来自差分磁强计（11,12）的输出的背景磁场。 类似地，可以使用平均磁强计立方体和多个不同的磁力计立方体来构建高阶梯度计。 梯度计可以在广泛的领域得到应用，如地质学和医学。
