I learned in October 2022’s Breakthrough that the spikes of stars in high-power photos are called diffraction spikes. Why do they appear as two crosses at 45 degrees to each other? The diffraction ...

The demonstrated QCMs can reconstruct holographic images and display diffraction patterns simultaneously. Silicon nanofins are arranged in the Penrose tiling pattern as illustrated by the 2D color ...

Researchers developed a holographic data storage approach that stores and retrieves information in three dimensions by ...

A pattern of distorted lines is visible as a reflection in this close-up view of a human eye. By observing the deformation of illumination patterns reflected off the eye's surface, researchers in ...

Fundamentals of electron diffraction -- Relation between crystal lattice, stereographic projection and reciprocal lattice -- Indexing polycrystalline and single-crystal patterns -- Orientation ...
