One of the simplest and most beautiful naturally occurring patterns can be observed when light is shined through a pair of slightly misaligned periodic structures. This phenomenon, known as the moiré ...

White light interferometry (WLI) is a non‐contact optical method that exploits the interference of broadband light to obtain high‐resolution three‐dimensional maps of surface topographies. By ...

Scientists have demonstrated a sort of holographic strip that splits a single laser beam into five bespoke beams that create an optical knot. The work shows that optical knots could be used as a ...

Researchers discovered brand new interference patterns in twisted two-dimensional tungsten ditelluride lattices. These patterns can be tuned to look like periodic spots or even one-dimensional bands ...
