The sub-millimetre non-uniformity measurement of residual and coil-generated field in the magnetic shield using atomic vapor cell
Chen Liu, Haifeng Dong, Junjun Sang
Magnetic field source localization and imaging happen at different scales. The sensing baseline ranges from meter scale such as magnetic anomaly detection, centimeter scale such as…
Spin image of an atomic vapor cell with a resolution smaller than the diffusion crosstalk free distance
Haifeng Dong, Jingling Chen, Jimin Li +4
The diffusion crosstalk free distance is an important parameter for spin images in atomic vapor cells and is also regarded as a limit on the spatial resolution. However, by modulat…
Spatial dynamics analysis of polarized atom vapor
X. Y. Hu, H. F. Dong, H. C. Huang +2
We analyze the spatial dynamics of polarized atom vapor and present a mathematical method to eliminate the diffusion effect partially. It is found that the diffusion effect of pola…
Atomic-signal-based zero field finding technique for unshielded laser-pumped atomic magnetometer
Haifeng Dong, Hongbo Lin, Xinbin Tang
We described a novel technique that can find the zero-field for unshielded laser-pumped atomic magnetometer using atomic signal itself. By comparing light density of pump beam afte…
