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 ...

The holographic 3D display is an important technology with excellent application prospects. However, the viewing angle of holographic 3D displays is currently limited by existing strategies. This ...

THE optical system of a high performance electron microscope can also be used for investigations other than simple transmission microscopy. One such ‘unconventional’ application is low-angle electron ...

If you are like me then you might not always get caught up in some of the super technical aspects of photography. One aspect of photography I recently investigated was the loss of sharpness caused by ...

Researchers have developed an atom-diffraction imaging method with micrometer spatial resolution, which may allow new applications in material characterization. Microscopy with atoms offers new ...
