What happens when a wave passes through some opening? It diffracts - or you like, you could say "bends". If the size of the opening is comparable to the wavelength of the wave, the bending can be ...

If you think of a single atom as a grain of sand, then a wavelength of visible light—which is a thousand times larger than ...

Researchers at University of Tsukuba have achieved a significant breakthrough by employing scatterometry, a technique ...

The diffraction spikes so familiar to us in space images are an intrinsic property of the telescope. Reflecting telescopes have two mirrors: a large primary and a smaller secondary. Light hits the ...

The spectrum of laser technologies available to hackers has gradually widened from basic gas lasers through CO2 tubes, diode ...

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 ...

Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

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 ...

[The Thought Emporium] has been fascinated by holograms for a long time, and in all sorts of different ways. His ultimate goal right now is to work up to creating holograms using chocolate, but along ...
