THE VIDEO SHELF · photon sieves and diffraction optics
Light Waves Visualized using Photon Sieves.
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.
Why HN readers recommended it
HN points to it for a clear explanation of photon sieves versus Fresnel lenses and for showing what interference patterns actually look like.

In Photon SieveRegarding 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 …
