A combined team of engineers from Jiangsu University and Harvard University used a non-destructive, light diffraction fingerprint technique to detect viral infections in cells. Their paper is ...

Until recently, it was widely believed among physicists that it was impossible to compress light below the so-called diffraction limit (see below), except when using metal nanoparticles, which ...

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 ...

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 ...

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 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 ...

Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...
