Diffraction occurs when a wave encounters an obstruction in its path and will change direction, or wrap around it. In ocean waves, we see this occur when a wave encounters an object like a jetty and ...
Making a perfect lens that produces flawless images has been a dream of lens makers for centuries. In 1873, Ernst Abbe discovered a fundamental 'diffraction limit' in optics: whenever an object is ...
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 ...
When a laser beam is incident on many small objects such as lycopodium powder, the resulting diffraction pattern is similar to the diffraction pattern of a small circular aperture (Airy's disk pattern ...
Stars in the new images from the James Webb Space Telescope look sharper than they did before. And I’m not just talking about the image quality, which is astounding. I’m talking about the fact that ...
A new atom camera uses one ultracold rubidium atom to map light intensity and polarization with spatial resolution below 100 nanometers.
When a laser beam is incident on a narrow opaque object such as a fine wire or a strand of hair, the resulting diffraction pattern is similar to the diffraction pattern of a slit of the same width as ...
The author examines the process of method development, with reference to ISO 13320:2009 and relevant monographs from the United States and European pharmacopoeias. Particle size is a critical quality ...

Looping lasers whisk molten metals together during 3D printing, opening new alloy design route
Like modern-day alchemists, metallurgists are constantly discovering and perfecting recipes for better alloys. A crucial step in those recipes is to get different metals to mix evenly. Unveiling a new ...
Diffraction gratings are beautiful things, bending transmitted and reflected light and splitting it into its component wavelengths to create attractive iridescent rainbow patterns. It’s the same ...
We’ve seen just about every possible way to make a clock here at Hackaday over the years. So it’s rare to have a first, but ...
