Abstract
We investigate the near-field inverse scattering problem with evanescent wa ves. An analytic solution to this problem within the weak-scattering approx imation is used to show that the usual Rayleigh limit may be overcome even when measurements are made without phase information. Applications to a nov el form of three-dimensional microscopy with subwavelength resolution are d escribed.
