Description

  

      Optische        Vorrichtung    für     plastische        Bildvermittlung.       Gegenstand     vorliegender        Erfindung    ist  eine optische Vorrichtung für plastische Bild  vermittlung, mit welcher zum Beispiel ge  wöhnliche     Bilder    und Photographien mit  einem plastischen Effekt und Stereobilder voll  kommen plastisch wahrgenommen werden.  



  Dies wird     erfindungsgemäss    erreicht mit  tels mindestens eines aus einem durchsich  tigen Material bestehenden,     geschliffenen     prismatischen Körpers.  



  Zwei Ausführungsbeispiele der     erfindungs-          gemässen    Vorrichtung sind in den     Fig.    1 und 2  dargestellt, deren     Querschnitte    die Form  eines     stumpfwinkligen    Dreiecks (Fug. 1) bzw.  eines Rhombus (Fug. 2) besitzen. Die Flä  chen F der Körper A sind     geschliffen.     



  Der prismatische Körper A kann auch aus  zwei Teilen bestehen, welche zusammen  gefügt     die    Körper mit den erwähnten Quer  schnitten ergeben (Fug. 3 und 4).  



  Wird durch einen derartigen prismati  schen Körper A ein Bild oder ein Gegen  stand B betrachtet, indem man den prisma  tischen Körper A unmittelbar an die Augen  heranbringt, so sieht man das Bild oder den  Gegenstand B     infolge    der Strahlenbrechung  doppelt als B' und BR nebeneinander (Fug. 5).  



  Verändert man bei dieser Betrachtungs  weise den Abstand zwischen den Augen und  dem prismatischen Körper A durch Vor- oder       Rückwärtsschieben    des letzteren, so ver  schmelzen in einem bestimmten Punkte die    beiden     Bilder    B' und BR zu einem einzigen,       nunmehr        vergrösserten    und mit     einem    pla  stischen Effekt     wahrgenommenen    Bild B 2  (Fug. 6).

   _  Verwendet man bei der gleichen Betrach  tungsweise Stereobilder, deren     Teilbilder    aus  getauscht sind (linkes     Teilbild    rechts, rechtes       Teilbild        links),    so     wird    nunmehr ein vollkom  men plastisches     Bild        wahrgenommen.     



  Eine erhöhte Wirkung     wird    erreicht,  wenn,     wie    in     Fig.    7 gezeigt, zwei     Gläshnsen    L  vor den prismatischen Körper A angebracht  werden. Durch Verwendung mehrerer prisma  tischer Körper A, welche in     Blickrichtung     hintereinander angeordnet sind,     und    unter  Verwendung     eines    Linsenpaares, lassen sich  beispielsweise die in     Fig.8    dargestellten       Kombinationen        erstellen.     



  Die beschriebene optische Vorrichtung  eignet sich     für    die Betrachtung von     Bildern     im Klein- und im Grossformat, beispielsweise  auch für projizierte     Bilder    im Grossformat,  und ist     hauptsächlich    für     Stereodoppelbilder     gedacht. Sie ist     für        Einzel-    wie auch. für gleich  zeitige     Kollektivbetrachtungen    anwendbar.



      Optical device for plastic image conveyance. The present invention is an optical device for plastic image mediation with which, for example, ordinary images and photographs with a plastic effect and stereo images are fully perceived plastic.



  According to the invention, this is achieved by means of at least one ground prismatic body made of a transparent material.



  Two exemplary embodiments of the device according to the invention are shown in FIGS. 1 and 2, the cross sections of which have the shape of an obtuse triangle (Fug. 1) or a rhombus (Fug. 2). The surfaces F of the body A are ground.



  The prismatic body A can also consist of two parts which, when joined together, result in the body with the aforementioned cross-sections (Fug. 3 and 4).



  If an image or an object B is viewed through such a prismatic body A by bringing the prismatic body A directly up to the eyes, the image or the object B is seen twice as B 'and BR side by side due to the refraction of the rays ( Fug. 5).



  If you change the distance between the eyes and the prismatic body A by moving the latter forwards or backwards, the two images B 'and BR merge at a certain point into a single, now enlarged and with a plastic effect perceived image B 2 (fug. 6).

   _ If stereo images are used in the same way of viewing, the partial images of which have been swapped (left partial image on the right, right partial image on the left), a completely three-dimensional image is now perceived.



  An increased effect is achieved if, as shown in FIG. 7, two glasses L are attached in front of the prismatic body A. By using several prismatic bodies A, which are arranged one behind the other in the viewing direction, and using a pair of lenses, the combinations shown in FIG. 8 can be created, for example.



  The optical device described is suitable for viewing images in small and large format, for example also for projected images in large format, and is mainly intended for stereo double images. She is for single as well. applicable for simultaneous collective considerations.
