In 1873, Ernst Abbe proposed the famous diffraction limit theory, stating that the resolution of an optical system is limited by the light wavelength ...

Abstract: The coherent diffraction imaging (CDI) is a beamline microscopy technique based on diffraction that removes the resolution limit imposed by conventional imaging optics. However, the axial ...

The imaging resolution has long been constrained by the Abbe-Rayleigh diffraction limit. While the 2014 Nobel Prize recognized fluorescence microscopy, achieving single-shot, label-free far-field ...

Atoms measure roughly 0.1 nanometers across, a scale so small that scientists spent more than six decades developing ...
