Abstract
A system, comprising a target, a first receiving coil array, and a second receiving coil array. The target includes: (i) a first array of conductive features that are arranged in a line or arc and separated from one another by voids, and (ii) a second array of conductive features that are arranged in a line or arc and separated from one another by voids, the conductive features in the first array being staggered with respect to the conductive features in the second array. The first receiving coil array is configured to sense a first magnetic field that is associated with the first array of conductive features. The second receiving coil array is configured to sense a second magnetic field that is associated with the second array of conductive features.
