Abstract:
A distance measurement system is provided. The distance measurement system includes at least one resonant circuit, at least one magnetic element with predetermined magnetic properties, a transmitter operable to transmit an electromagnetic pulse, a receiver operable to detect oscillations emitted by said resonant circuit in response to said electromagnetic pulse, and an analyzer operable to analyze an amplitude envelope property of said oscillations, to thereby determine a distance between the resonant circuit and the magnetic element.
