Here’s a great picture from [Jelly & Marshmallows] that shows off the wild effects of melted chocolate poured onto a diffraction grating. A diffraction grating is a kind of optical component whose ...

Diffraction gratings are curious things. Score a series of equally spaced tiny lines in a surface, and it will cause reflected or transmitted light to bend and separate into its component wavelengths.

The integration of beam splitters and grating structures is central to contemporary developments in optical engineering. These devices, which manipulate light via diffraction and interference, are ...

Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original ...

Scientists have observed “bending” atoms using a crystal grating—an experiment once believed impossible at the high energies required. The authors of a new, non-peer reviewed study detail how the a ...

Lighting and display manufacturers must ensure their products are consistent in their light output, making them reliant on effective quality control methods. Their products must be validated, and ...

Holographic 3D display completely avoids the side effects of the traditional 3D display, such as the dizziness and fatigue of viewers. Therefore, it has become the frontier and hotspot of the current ...

Ultrashort laser pulses—that are shorter than a millionth of a millionth of a second—have transformed fundamental science, ...
