Fluxgate magnetometer with pulsed excitation and sampled detection

摘要

the invention relates to a device for measuring magnetic field with a magnetometer to fluxgate, the device comprising: a magnetic sensor and magnetic sensor (110210) capable of delivering at least one output signal (s2), and has at least one magnetic core, means of exc development of the magnetic core, comprising means (120220 generators.420) able to emit a excitation signal (s1, s10) in the circuit and magnetic sensor, in the form of a sequence of pulses (125126225226), a sampling means (130230330430) of the output signal (s1) of the magnetic circuit (110210), further including means for following the issuance of at least one pulse of the pulse sequence.initiate acquisition of at least one output signal (s2) of the magnetic circuit by means of sampling for the duration of the stimulus. the invention also relates to a method implemented by this device.
