Abstract:
A device for measuring components of a magnetic field, comprising:a scalar magnetometer configured to continuously supply an output signal corresponding to a modulus of the magnetic field to be measured;at least two conductor windings placed around said scalar magnetometer, said conductor windings having axes oriented in different directions;at least two generators, each of said at least two generators being configured to continuously supply a current to one of said at least two conductor windings, said current having a frequency specific to said one of said at least two conductor windings; anda processing circuit configured to receive said output signal supplied by said scalar magnetometer,wherein said processing circuit comprises at least two synchronous demodulators, each of said at least two synchronous demodulators being configured to demodulate said output signal and to continuously supply a signal corresponding to a component of said magnetic field to be measured along an axis of one of said at least two conductor windings.
