The optical radiation force can deform dielectric material surfaces, such as photo-isometric azopolymers, due to their electric susceptibility, and the shape can be controlled by the artificial ...

In the famous double-slit experiment, an interference pattern consisting of dark and bright bands emerges when a beam of light hits two narrow slits. The same effect has also been seen with particles ...

In 1927, the term "picture element," later abbreviated to "pixel," appeared for the first time in the American technology magazine Wireless World. Today, pixels are everywhere: in computer screens and ...

The basics of digital logic are pretty easy to master, and figuring out how the ones and zeroes flow through various kinds of gates is often an interesting exercise. Taking things down a level and ...

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 ...

Scientists studying particle collisions at the Relativistic Heavy Ion Collider (RHIC) usually capture what happens when atomic nuclei smash into one another at nearly the speed of light. But even when ...

Inkjet printers are key technologies in manufacturing organic light-emitting diodes and quantum dot light-emitting diode panels, but precise measurement and control of inkjet droplets remains ...

QWP-based GP-SIDH architecture for artifact-suppressed full-color holography under broadband incoherent illumination: schematic overview (left) and video-rate phase retrieval with high-fidelity ...

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 ...
