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 ...

Diffraction gratings separate different wavelengths of light using a periodic pattern embedded in the grating. The diffraction pattern can affect the amplitude and/or phase of the incident light as ...

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 ...

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 ...

Researchers from Tsinghua University have developed a new angle-resolved analysis method for ultrafast liquid electron diffraction, offering a route to retrieve more complete three-dimensional ...

"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 ...
