Abstract
A non-contact measurement method for a relative displacement or relative positioning of a first object relative to a second object, in which: at least one transmitting coil, placed on the first object, is excited by an alternating excitation signal, at least one alternating electronic output signal, generated by mutual inductance in at least one receiving coil, is detected; the at least one receiving coil being placed on the second object and in a magnetic field created by the at least one transmitting coil, and the relative displacement of the first object is determined relative to the second object using the at least one alternating electric output signal generated on the at least one receiving coil.
