A Review of Super-Resolution Imaging through Optical High-Order Interference [Invited]

Resolution is crucially important for optical imaging, which happy camper dog shirt defines the smallest spatial feature of object that can be delivered by light wave.However, due to the wave nature of light, optical imaging is of limited resolution, widely known as Rayleigh limit or Abbe limit.Nevertheless, this limit can be overcome by considering the loopholes in the derivation of the Rayleigh limit, such as light–matter interaction, structured illumination, and near-field interference.In contrast to the conventional single-photon interference, multi-photon amplitudes responsible for optical high-order interference could be designed to possess bar vac 7 somnus a reduced effective wavelength, enabling the breakthrough of the Rayleigh limit.In this review, we will present recently developed super-resolution imaging schemes based on optical high-order interference, and discuss future perspectives.
