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 here we are with [Twisted & Tinned], who’s made a novel clock with a ...

In this video I talk about diffraction gratings and how they work. I show you how you can use them to make diffraction patterns on chocolate or other shiny materials. Trump faces backlash over Coast ...

Abstract: Photolithography has a resolution limit of the incident wavelength that is generated by the diffraction of light. Surface plasmon (SP) is a recently proposed nanolithography technology that ...

Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated a new way to structure light in custom, repeatable, three-dimensional patterns, ...

Optical dispersion occurs when the refractive index of a material changes with the wavelength of incoming light. This variation causes different colors to move at different speeds in transparent media ...

Peacock feathers are greatly admired for their bright iridescent colors, but it turns out they can also emit laser light when dyed multiple times, according to a paper published in the journal ...

Researchers have discovered a novel way that surface acoustic waves interact with magnetic materials, leading to a surprising asymmetric diffraction effect. This could revolutionize acoustic-based ...

ABSTRACT: We report a comprehensive numerical study of super resolution (SR) structured illumination microscopy (SIM) utilizing the classic Heintzmann-Cremer SIM process and algorithm. In particular, ...

Implicit periodic structure in phase-only holograms will result in many diffraction orders in the diffraction field. We analyzed the diffraction pattern from a phase gratings point of view and proved ...
