<p>In an exemplary embodiment, one or more flux pickups with ferromagnetic properties, preferably Hall generators provided with antennas, are provided for the detection of a field flux or of a change of field flux proceeding from a field generator. Magnetization pulses (I2) are provided in periodic sequence to the flux pickups (I through VIII), the pulse height and width (tim) being selected in such manner that the saturation field strength (Ms) of the flux pickups is therewith achieved, so as to produce a maximum residual magnetization (MR). The flux pickups (I through VIII) are preferably driven by means of pulse-shaped signals (I1), with the magnetization pulses being supplied in the pulse interval (is) of these signals synchronous to the pulse repetition rate. The method is particularly employed in gnathography for recording the lower jaw movement of a human being.</p> |
