Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The ...

One of the best known properties of light is that it diffracts, bending or spreading around objects that lie in its path. A familiar example is when a collimated beam of light passes through a small ...

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 ...

Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...

Nowadays, most studies utilizing diffraction contrast tomography, either in the lab or at the synchrotron, have concentrated on relatively low-aspect-ratio samples, usually rectangular or cylindrical ...
