Concept, design and implementation of widefield quantum sensing.
A) Overview of NV-based widefield quantum sensing: energy level diagram and atomic structure of NV centers; and the experimental apparatus of widefield quantum diamond microscope. L: Laser; DM: Dichroic Mirror; BS: Beam Splitter; M: Mirror;
B) A schematic showing the working principle of frame-based widefield quantum sensing, where a series of frames are output from a frame-based sensor recording both fluorescence intensity and background signals.
C) A schematic showing the working principle of proposed neuromorphic widefield quantum sensing, where the fluorescence changes are converted into sparse spikes through a neuromorphic vision sensor
