We introduce a non-intrusive far-field optical microscopy, which reveals the fine structure of an object through its far-field scattering pattern under illumination with topologically structured light containing deeply subwavelength singularity features. The object is reconstructed by a neural network trained on a large number of scattering events. We demonstrate resolving powers two orders of magnitude beyond the conventional “diffraction limit” of λ/2.

Abstract

We introduce a non-intrusive far-field optical microscopy, which reveals the fine structure of an object through its far-field scattering pattern under illumination with topologically structured light containing deeply subwavelength singularity features. The object is reconstructed by a neural network trained on a large number of scattering events. We demonstrate resolving powers two orders of magnitude beyond the conventional “diffraction limit” of λ/2.
