 The study shows that selective amplification of evanescent waves can be used to reconstruct truthful images of the near-field without perturbing it, allowing for sub-wavelength imaging with resolutions as low as lambda 7 and amplitude signal-to-noise ratios less than 25 dB between 0.18 to 1.5 ThZ. This procedure can be implemented with any near-field probe and greatly relaxes experimental requirements for sub-wavelength imaging at sub-optical frequencies, opening the door to non-invasive near-field scanning.
