The diffraction spikes so familiar to us in space images are an intrinsic property of the telescope. Reflecting telescopes have two mirrors: a large primary and a smaller secondary. Light hits the ...

Understanding optical resolution is key in microscopy, highlighting the diffraction limit and innovations in super-resolution ...

Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

It’s relatively easy to understand how optical microscopes work at low magnifications: one lens magnifies an image, the next ...

A U.K.-Portuguese research group is proposing a new solar cell design based on diffraction gratings – optical components that split and diffract light into several beams. They claim this could lead to ...

A technical paper titled “Scalable nanopatterning of organic light-emitting diodes beyond the diffraction limit” was ...

Twisted photonics: A bilayer of molybdenum trioxide supports highly unusual light propagation along straight paths when the two layers are rotated with respect to each other at the photonic magic ...

Particle size analysis is crucial to quality control and product development in a number of key industries including aerosols, construction, food and beverage, paint and coatings, and pharmaceuticals.

A pulse of light sets the tempo in the material. Atoms in a crystalline sheet just a few atoms thick begin to move—not randomly, but in a coordinated rhythm, twisting and untwisting in sync like ...

Researchers at Harvard University and Jiangsu University developed a technique for not only identifying infected cells, but also tracking the infection over time as the cells developed. They published ...
