Project of Absolute Three-Component Vector Magnetometer Based on Quantum Scalar Sensor

摘要

A project of vector magnetometer of new kind based on optically pumped quantum M_x-sensor placed in symmetrical magnetic coils system is proposed and mathematically proved. The device uses a new method of the fast precision measurement of three Earth magnetic field (EMF) vector components providing absolute accuracy of the order of 0.1 nT at 0.1 s sampling rate. Absoluteness here implies that the process of measurement changes the measured parameter, i.e., field component value, no more than by the value determined by the sensitivity of scalar sensor. The short-term resolution of the method is determined by the Mx-sensor sensitivity.
