Abstract
Section titled āAbstractāTime-resolved magnetic sensing is of great importance from fundamental\nstudies to applications in physical and biological sciences. Recently the\nnitrogen-vacancy (NV) defect center in diamond has been developed as a\npromising sensor of magnetic field under ambient conditions. However the\nmethods to reconstruct time-resolved magnetic field with high sensitivity are\nnot yet fully developed. Here, we propose and demonstrate a novel sensing\nmethod based on spin echo, and Haar wavelet transform. Our method is\nexponentially faster in reconstructing time-resolved magnetic field with\ncomparable sensitivity over existing methods. Further, the waveletās unique\nfeatures enable our method to extract information from the whole signal with\nonly part of the measuring sequences. We then explore this feature for a fast\ndetection of simulated nerve impulses. These results will be useful to\ntime-resolved magnetic sensing with quantum probes at nano-scales.\n
