Summary

[edit]
Description
Deutsch: Unsichtbarkeit mit Fresnel-Zylinder-Linsen
  • Beschreibung:
    • Da für das unsichtbar-Machen große Linsen benötigt werden,
    • kann man um Gewicht zu sparen Fresnellinsen verwenden.
    • Eine Zylinderlinse besteht aus Teilflächen eines
    • Zylindermantels, und bündelt das Licht auf eine Brennlinie.
    • In dieser Brennlinie befindet sich ein schmaler Planspiegel,
    • der das Licht zu einer zweiten Fresnel-Zylinder-Linse reflektiert.
    • Um zwei getrennte unsichtbare Zonen zu vermeiden,
    • werden zwei halbierte Fresnel-Zylinder-Linsen verwendet.
    • Im Gegensatz zu anderen Methoden der Unsichtbarkeit ist diese
    • Methode relativ platzsparend. Alle Bauteile stellen die Wandung
    • eines Quaders dar, und die Hälfte des Innenraumes ist unsichtbar.
    • Auch hier gilt, dass aus einem bestimmten Blickwinkel
    • nur noch der Hintergrund des Objektes, aber nicht das
    • Objekt selbst gesehen werden kann.

This physics image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.


It is recommended to name the SVG file “UNFRZYLI Unsichtbarkeit Fresnel Linsen.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
This physics image was uploaded in the JPEG format even though it consists of non-photographic data. This information could be stored more efficiently or accurately in the PNG or SVG format. If possible, please upload a PNG or SVG version of this image without compression artifacts, derived from a non-JPEG source (or with existing artifacts removed). After doing so, please tag the JPEG version with {{Superseded|NewImage.ext}} and remove this tag. This tag should not be applied to photographs or scans. If this image is a diagram or other image suitable for vectorisation, please tag this image with {{Convert to SVG}} instead of {{BadJPEG}}. If not suitable for vectorisation, use {{Convert to PNG}}.
