Development of three-axis vector atomic magnetometer with small dead zone
摘要
Abstract
In order to reduce the requirement of three-axis vector atomic magnetometers for the attitude control range of the motion platform,a scalar pump-probe atomic magnetometer with a smaller dead zone was selected for the vector atomic magnetometer based on the magnetic field rotation-modulation method.The improved vector atomic magnetometer had a smaller dead zone and had the potential to be used on a stationary or slow-moving platform.Firstly,the working principle of the vector atomic magnetometer based on the magnetic field rotation-modulation method was introduced.Secondly,the distribution of dead zones of the vector atomic magnetometers was analyzed when the scalar atomic magnetometer was select-ed as an Mx type optical pump magnetometer or a pump-probe type atomic magnetometer.Finally,the technical specifications of the three-axis atomic magnetometer with a small dead zone were validated near the geomagnetic field.When the three-axis vector atomic magnetometer measures the vector magnetic field near 40 000 nT,the sensitivity of measuring total fields is less than 1 nT/Hz1/2(@0.1 Hz),the sensi-tivity of measuring angles is less than 0.1°/Hz1/2(@0.1 Hz),and the proportion of dead zone in spatial sol-id angle is less than 12%.The vector magnetometer described in this article has the technical characteris-tics of dynamic continuous measurement,wide range and small dead zone.关键词
