Abstract
Disclosed herein are systems and methods for a three-dimensional (3D) non-contact position sensor. A system includes a magnetic target coupled to and/or integrated with a target object and a position sensor comprising a plurality of magnetometers configured to provide a set of magnetic flux values corresponding to a magnetic field generated by the magnetic target. A logic device receives the set of magnetic flux values provided by the plurality of magnetometers of the position sensor and determines a position and/or orientation of the target object based, at least in part, on the received set of magnetic flux values. The position and/or orientation of the target object may be used as feedback to help position and/or orient the target object according to a desired position and/or orientation or to track its position accurately in real-time.
