Interscale Mixing Microscopy: numerically stable imaging of wavelength- scale objects with sub- wavelength resolution and far field measurements
Abstract
We present an imaging technique that allows the recovery of the transparency profile of wavelength-scale objects with deep subwavelength resolution based on far-field intensity measurements. The approach, interscale mixing microscopy (IMM), relies on diffractive element positioned in the near-field proximity to the object, to scatter information carried by evanescent waves into propagating part of the spectrum. A combination of numerical solutions of Maxwell equations and nonlinear fitting is then used to recover the information about the object based on far-field intensity measurements. The potential of the developed formalism to recover wavelength/20 features of wavelength-scale objects in presence of up to 10% noise is demonstrated.
