Description
  • V nedávné době byly složené vírové svazky generované pomocí prostorového modulátoru světla pracujícího v dynamickém režimu studovány jako perspektivní nosiče informace. V článku je navržena a experimentálně testována pokročilá metoda využití optických vírů pro přenos informace. Její princip spočívá v návrhu sofistikované fázové masky, pomocí níž je informace kódována a dekódována. V navrhovaném komunikačním kanálu je využita fotolitograficky vyrobená maska pro generaci složeného vírového pole. Dynamiky kódování a dekódování informace je dosaženo spínáním intenzity matice bodových zdrojů osvětlujících fázovou masku. (cs)
  • Recently, composed vortex fields generated by means of a spatial light modulator working in a dynamical regime have been examined as perspective information carriers. In this paper, an advanced optical set-up utilizing vortices for transfer of information is proposed and experimentally verified. Its operation is based on a sophisticated design of phase-only masks enabling information encoding and decoding. In the proposed vortex communication channel, the photolithographically prepared masks are used for generation of a composed vortex field carrying information. Dynamics of information encoding and decoding is achieved by switching of an array of light sources illuminating the phase masks.
