Self-Calibrating Vector Atomic Magnetometry through Microwave Polarization Reconstruction
Self-Calibrating Vector Atomic Magnetometry through Microwave Polarization Reconstruction
Atomic magnetometry is one of the most sensitive ways to measure magnetic fields. We present a method for converting a naturally scalar atomic magnetometer into a vector magnetometer by exploiting the polarization dependence of hyperfine transitions in rubidium atoms. First, we fully determine the polarization ellipse of an applied microwave …
