Abstract
An instrument for detecting a position in space may include a proof mass arranged along an input axis, an electromagnetic coil arranged at each end of the proof mass and configured to suspend the proof mass therebetween, wherein the proof mass is configured to rotate along the input axis, and at least one rotation sensor configured to detect the rotational position of the proof mass.
