At f/8, every lens produces an identical 10.7-micron diffraction blur on your sensor regardless of focal length or aperture ...

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 ...

Diffraction is a classic optical phenomenon accounting for light propagation. The efficient calculation of diffraction is of significant value towards the real-time prediction of light fields. The ...

Obtain, evaluate, and communicate information about the properties and applications of waves. SP4.b Develop and use models to describe and calculate characteristics related to the interference and ...

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 ...

[The Thought Emporium] has been fascinated by holograms for a long time, and in all sorts of different ways. His ultimate goal right now is to work up to creating holograms using chocolate, but along ...

Beauty is in the eye of the beholder, and when it comes to “sunbursts” in photos – those points of light with rays streaking out of them – people often have polarizing views. Optical diffraction is ...
