Turning diffraction into a tool The technique uses a device that can only turn pixels on and off. Conventional thinking suggests that such a system can create only two levels of light intensity. The ...

Scientists have advanced metasurface technology by developing a new design that simultaneously projects holographic images and creates special diffraction patterns with ten-fold rotation symmetry of ...

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 ...

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

Researchers at the European XFEL and ETH Zurich have developed two methods, including a pixel-based colour separation ...

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 ...

Researchers have generated high-quality atom diffraction data from graphene, which could lead to new ways to measure surface interactions. A beam of neutral atoms striking a material can produce a ...

"For us, it became an enabler." By carefully designing patterns smaller than the diffraction limit, the team was able to precisely control how much light reached different parts of the printing area ...
