Caption

Experimental demonstration. The measurement protocol, raw datasets and obtained ODMR spectrum (of the central point of ROI) using frame-based A, C, E and event-based sensor B, D, F respectively. The insert in F shows raw event frames (by accumulating events of 1ms range) at three different frequency points. The spectra in E and F are fitted with the Lorentzian and its derivative functions, respectively, from which the resonance frequency f0 is extracted (f0*is the averaged result from forward and backward sweeping; Error represents the standard deviation from 10 repeated measurements)
