Diffraction

...need for any lenses, microscope-objectives or any mechanical scanning. In this high-throughput lensless imaging scheme, the classical diffraction pattern (i.e., the shadow) of each micro-particle within the entire sample volume is detected in...

...the Berkeley Lab. The same lab group, led by materials scientist Xiang Zhang, demonstrated a similar feat in 2007 by breaking the "diffraction limit" that usually prevents researchers from imaging features smaller than typical light waves.

...uniquely engineered structures give rise to extraordinary optical properties - hyperlenses make it possible to overcome the so-called "diffraction limit" by imaging features that are significantly smaller than the wavelengths of incident...

...a crystal, it is then placed in front of a beam of x-rays, which diffract when they strike the crystal's atoms. Based on the pattern of diffraction, scientists can reconstruct the shape of the original molecule. In this case, the team...

...wave that spreads out through the water. If it hits a microscopic object - a bacterium, say - further diffraction occurs. The spherical wave and the diffraction pattern created by the microscopic object interfere to create a pattern that is...

...ISO setting of 200. To create the sharp starburst effects on the bridge lights, he shrunk his aperture down to f/14 which creates light diffraction. The smaller the aperture (at f/12 or smaller), the more pronounced the starburst effect (also...
