Recent scientific advancements have opened new opportunities for the close observation of physical phenomena. Researchers at University of Cambridge and University of Newcastle recently introduced a ...

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 ...

In the field of scanning electron microscopy (SEM), the electron backscatter diffraction (EBSD) method has developed into a robust tool for the crystallographic analysis of materials. Specifically, ...

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 ...

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 ...

A once purely mathematical tiling breakthrough has revealed an unexpected optical effect when recreated at the nanoscale.

X-ray diffraction (XRD) is a non-invasive method for determining that can be used in phase analysis investigations of crystalline materials. Image Credit: AgriTech/Shutterstock.com The essential idea ...

"Often, the diffraction limit is considered a nuisance," Saha said. "For us, it became an enabler." By carefully designing patterns smaller than the diffraction limit, the team was able to precisely ...
