Abstract:
1. A magnetic field measuring device, equipped with a fluxgate magnetometer, the device comprising: a magnetic sensor equipped with at least one magnetic core and a plurality of windings, and configured to deliver at least one output signal; pulse generating means for emitting at least one excitation signal at the input of the magnetic sensor, in the form of a succession of excitation pulses, one excitation pulse of said excitation pulses having a duration at least 50 times less than a period of said at least one excitation signal; sampling means for sampling the output signal of the magnetic sensor; and means for, following the emission of at least one excitation pulse of said succession of excitation pulses and during the duration of said at least one excitation pulse, triggering at least one acquisition of the output signal of the magnetic sensor by said sampling means.
