Century-Old Challenge Of “Atomic Diffraction” Finally Solved Thanks To Graphene This experiment is “fundamentally different” from all previous atomic diffraction experiments.

A rectangular aperture was easily got by cutting slits in two pieces of tinfoil with a razor and placing one over the other with the slits at right-angles, while for a triangular aperture three ...

The diffraction in this case occurs in the temporal domain, creating frequencies in the frequency spectrum when a separate laser applies a brief probing pulse.

A new publication from Opto-Electronic Advances, 10.29026/oea.2023.230039 discusses diffraction-limited visible imaging for large aperture telescopes.
