Abstract
Section titled “Abstract”The localization and tracking of tiny magnetic source hold great potential for applications in the fields of medical and scientific research. However, cross-order-of-magnitude localization using millimeter sensor is an open problem. In this article, we proposed a precise localization method for the tiny magnetic source that breaks through the limited field-of-view of the optical quantum sensor imaging. The position of the magnetic source is uniquely resolved by the construction of a magnetic gradient tensor (MGT) based on the vector magnetic field (2.7 <inline-formula xmlns:mml=“http://www.w3.org/1998/Math/MathML” xmlns:xlink=“http://www.w3.org/1999/xlink”> <tex-math notation=“LaTeX”>$\times $ </tex-math></inline-formula> 2.7 mm, pixel size: <inline-formula xmlns:mml=“http://www.w3.org/1998/Math/MathML” xmlns:xlink=“http://www.w3.org/1999/xlink”> <tex-math notation=“LaTeX”>$3.45~\mu \text{m}$ </tex-math></inline-formula> ) obtained by nitrogen-vacancy (NV) color centers in a diamond. A 3 mm diameter magnetic source is accurately located within a spatial range of 5 cm with a mean error of 8%. In addition, the limitations and influencing factors of the NV-MGT localization method are theoretically discussed. The results provide insight into the localization of tiny magnetic sources and extend the application of quantum sensor.
