Summary
[edit]DescriptionFork hologram with charge 1.svg |
English: Pitch-fork hologram that is used to create light beams with an optical vortex whose topological charge is equal to 1. Such beams carry one unit of orbital angular momentum. Čeština: Vidlicový hologram, jenž je používán pro tvorbu světelných svazků s optickým vírem, jehož topologický náboj je roven jedné. Takové svazky nesou jednotkový orbitální moment hybnosti. |
