    摘要: A method of detection of a distance variation with respect to an axis of at least one point of an object rotating around this axis by a terminal at a fixed position with respect to the axis and capable of emitting a radiofrequency field for at least one resonant circuit attached to the object. The method includes the steps of measuring and recording, on the terminal side, a maximum value of a quantity representative of the coupling between an oscillating circuit of the terminal and the at least one resonant circuit; and detecting a variation of this periodic maximum.
