Description

werden. Ferner ist es bekannt, bei Leuchtkarten die Lageaintragung auf einer Plexiglasabdeckung vorzunehmen, die mit einer Flutlichtbeleuchtung ausgerüstet ist. Durch Abschalten der Beleuchtung der Landkarte kann der Lageplan allein als Leuchtbild dargestellt werden. Durch die verhältnismäßig dicke Plexiglasecheibe tritt aber eine störende Parallaxe auf. Außerdem ist die Einrichtung durch die rlutlichtbeleuchtung aufwendig und auch unbeques, da der örtliche Bearbeiter zur Geländebeurteilung jeweils wieder die Beleuchtung der Landkarte einschal- ten muß. will. It is also known to enter the position of light cards on a plexiglass cover that is equipped with floodlights. By switching off the lighting on the map, the site plan can be displayed as a light image alone. Due to the relatively thick Plexiglas pane , however, an annoying parallax occurs. In addition, the device is complicated by the rlutlichtbeleuchtung and unbeques because the local editor th each again having the lights of the map to terrain evaluation must.

Diese Mängel werden erfindungsgemäß dadurch behoben, daß auf eine von hinten durchleuchtete Landkarte, Zeich- nung oder Vorlage eine@Polarisationsfolie gelegt, auf diese eine Fernsehkamera gerichtet und vor deren Ob- jektiv eine weitere Polarisationsfolie optisch senk- recht zur ersten angeordnet wird, und daß weiterhin auf die Polarisationsfolie über der Landkarte, Zeich- nung oder Vorlage mit einem geeigneten Stift, z.». Fettstift oder rilzschreiber, Lagepläne, Skizzen od.dil. gezeichnet und/oder vorbereitete taktische Zeichen aus geeigneten rolien aufgelegt werden, wobei an den Spuren dieser dt@fte das polarisierte Licht gestreut und dadurch depolarisiert bsw. die Polarisationsart des Lichtes durch die Doppelbrechung in den ge- eigneten rolien derart verändert wird, daß für die ferns ehkamera ein hell leuchtender Lageplan, eine ökizze@od.dgl. auf dunkles Hintergrund sicht- bar ist. Auf diese Veise bleibt die Karte, Zeichnung oder Vorlage für den örtlichen Betrachter deutlich sichtbar, während sie für die rernsehkamera unsicht- bar ist. These deficiencies are remedied according to the invention in that a polarizing film is placed on a map, drawing or template that is illuminated from behind, a television camera is directed at it and a further polarizing film is arranged optically perpendicular to the first in front of its lens, and that continue on the polarization film over the map, drawing or template with a suitable pen, e.g. ». Grease pen or felt pen, site plans, sketches or dil. drawn and / or prepared tactical signs from suitable foils are applied, the polarized light being scattered on the traces of these dt @ fte and thus depolarized bsw. The type of polarization of the light is changed by the birefringence in the suitable foils in such a way that a brightly shining site plan for the television camera , an ecizze@od.dgl. is visible on a dark background . In this Veise the map, drawing or template for the local viewer remains clearly visible while she is rernsehkamera invisible for.
