For example, two-photon microscopy is capable of resolving sub-wavelength features because it demonstrates amplitude super-resolution. There are many other primarily scanning techniques that are based on sharp amplitude dependence in order to produce high-resolution images pixel by pixel. Something similar could be implemented here given our phase super-resolution where one would have to scan a beam of light across a sample and measure phase shifts on a point-by-point basis. The finite size of the scanning laser beam would have to be deconvoluted out of the final image.
