Abstract

Optically pumped magnetometers are scalar magnetometers which are particularly suitable for mobile applications for which it is necessary to use an isotropic sensor. Our group has recently designed a new helium magnetometer with reduced sensor orientation effects. In this paper, we present the results about frequency spatial isotropy and show frequency effects smaller a 240 pT.
