I am always on the lookout for ideas for simple test and measurement instruments that can be used on my workbench. Over the years, I have built dozens of little test instruments and home lab ...

Photonics researchers have introduced a novel method to control a light beam with another beam through a unique plasmonic metasurface in a linear medium at ultra-low power. This simple linear ...

A chip‑scale laser array with integrated beam shaping enables ultrafast, energy‑efficient optical wireless links for indoor ...

Particle Image Velocimetry (PIV) and optical flow methods represent two cornerstone approaches in experimental fluid dynamics and motion estimation. PIV employs tracer particles seeded in a fluid, ...
