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 ...

In 1873, the German physicist Ernst Abbe realized that the resolution of optical imaging instruments, including telescopes and microscopes, is fundamentally limited by the diffraction of light.

It is necessary to adjust the position of the electron beam as the voltage is varied. It is worthwhile to contrast the diffraction of electrons with the diffraction of light by a two dimensional grid.

Ultrafast electron imaging reveals never-before-seen nuclear motions in hydrocarbon molecules triggered by light. The ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

Q: What are diffraction gratings? A diffraction grating is an optical component for spectroscopy that splits light into different wavelengths. A typical diffraction grating has thousands of ...

The difference is that in a lycopodium powder diffraction, light gets diffracted from the edges of the tiny powder particle, creating irregular speckled pattern. When a focusing lens is placed in ...

Metasurfaces have the potential to fundamentally improve optical systems in our everyday lives. By controlling light more precisely, they drive compact, multi-functional solutions. Researchers have ...

The choice between electron diffraction and XRD depends on the specific requirements of the study, such as the need for high spatial resolution, sensitivity to light elements, or the nature of the ...

Depending on how an object interacts with light, it could appear vividly colored ... of a meter thick—without relying on traditional diffraction methods to retain the light within the material.

This NASA/ESA Hubble Space Telescope image features a sparkling spiral galaxy paired with a prominent star, both in the ...
