Overview

Huygens Optics shows how DIY photon sieves shape a laser's wave front, explaining how they differ from zone plates and how aperture count affects the focal point, with time-resolved visualizations of the diffraction.

On Hacker News

HN points to it for a clear explanation of photon sieves versus Fresnel lenses and for showing what interference patterns actually look like.

Regarding waves and interference, have a look at this video: [VIDEO] . It shows how the interference patterns actually look. Yes, the wave is 3D and the interference patterns can be kind of like checker board. We are usually considering a 2D example because it is simpler to visualize and analize. > how do we know that entanglement is the result of 'spooky action at a distance' and not the result of creating two entangled particles? A very high-level explanation is that we know this because quantum computers work (even though right now we can't build them big enough to be useful) and it can't be explained by any classical effects.
