Abstract
A detector is provided to measure the relative position of bodies along a measurement path comprising a first inductive target attached to a first body and arranged to face a first winding attached to a second body; a second inductive target attached to the first body arranged to face a second winding attached to the second body; wherein the targets extend along the measurement path and their extent orthogonal to the measurement path varies such that comparison of the windings inductances indicates the relative position of the two bodies.
