The video shows a simulation of a phenomenon called "speckle". It's best known as the granular interference pattern observed if we shine a coherent light of a laser at a diffuser. You can also observe it from a medium that contains small scattering particles. The simulation shows that it is caused by small phase differences that are introduced in the light by non-uniformity of a medium The green laser speckle image is taken from Wikipedia (copyrights Steve Jurvetson) and shown here under the Creative Commons license 2.0 (https://creativecommons.org/licenses/by/2.0/) Simulations made using the Python code suplied by @DiffractionLimited #physics #light
