Abstract
Section titled “Abstract”The rapid tracking of magnetic target holds significant importance in biomedicine, precision instrumentation, materials science, and more. The diamond nitrogen vacancy ( <italic xmlns:mml=“http://www.w3.org/1998/Math/MathML” xmlns:xlink=“http://www.w3.org/1999/xlink”>NV</i> <sup xmlns:mml=“http://www.w3.org/1998/Math/MathML” xmlns:xlink=“http://www.w3.org/1999/xlink”>-</sup> ) color centers exhibit magnetic field detection effect. They have shown high sensitivity, calibration-free nature, easy readout, and operability at room temperature. This paper presents an approach to rapidly induce magnetic fields based on the <italic xmlns:mml=“http://www.w3.org/1998/Math/MathML” xmlns:xlink=“http://www.w3.org/1999/xlink”>NV</i> <sup xmlns:mml=“http://www.w3.org/1998/Math/MathML” xmlns:xlink=“http://www.w3.org/1999/xlink”>-</sup> color centers ensemble without microwave. We demonstrated the magnetic-field-dependent photoluminescence (PL) of the <italic xmlns:mml=“http://www.w3.org/1998/Math/MathML” xmlns:xlink=“http://www.w3.org/1999/xlink”>NV</i> <sup xmlns:mml=“http://www.w3.org/1998/Math/MathML” xmlns:xlink=“http://www.w3.org/1999/xlink”>-</sup> color centers ensemble quantum system, and applied it wide-field imaging. By expanding the magnetic dipole model, we achieved rapid three-dimension (3D) tracking imaging technology of micro-sized magnetic target. Results show the <italic xmlns:mml=“http://www.w3.org/1998/Math/MathML” xmlns:xlink=“http://www.w3.org/1999/xlink”>NV</i> <sup xmlns:mml=“http://www.w3.org/1998/Math/MathML” xmlns:xlink=“http://www.w3.org/1999/xlink”>-</sup> color centers ensemble’s high dynamic sensing capabilities for magnetic fields, providing a wide field of view (3000 μm × 3000 μm) with a time resolution of 5 ms and a magnetic detection sensitivity of 0.5 μT/√Hz. Furthermore, it eliminated the influence of microwaves and reduced the experimental equipment requirements. These findings offer a direction for rapid tracking the magnetic target based on <italic xmlns:mml=“http://www.w3.org/1998/Math/MathML” xmlns:xlink=“http://www.w3.org/1999/xlink”>NV</i> <sup xmlns:mml=“http://www.w3.org/1998/Math/MathML” xmlns:xlink=“http://www.w3.org/1999/xlink”>-</sup> color centers ensemble.
