Deeply subwavelength optical imaging

Deeply subwavelength optical imaging
Deeply subwavelength optical imaging
We report the experimental demonstration of deeply subwavelength far-field
optical imaging of unlabelled samples with resolution better than λ/20. We beat the ~λ/2 diffraction limit of conventional optical microscopy several times over by recording the intensity pattern of coherent light scattered from the object into the far-field. We retrieve information about the object with a deep learning neural network trained on scattering events from a large set of known objects.

Abstract

We report the experimental demonstration of deeply subwavelength far-field
optical imaging of unlabelled samples with resolution better than λ/20. We beat the ~λ/2 diffraction limit of conventional optical microscopy several times over by recording the intensity pattern of coherent light scattered from the object into the far-field. We retrieve information about the object with a deep learning neural network trained on scattering events from a large set of known objects.
