1. A method for producing a transparent holographic display screen for displaying information with a display projection light beam emanating from a display projector, said method comprising the following steps:

  • (a) preparing a transparent carrier plate for passing wide band ambient light through said transparent carrier plate, (b) producing a primary volume hologram by recording a real projection display screen as an object of said primary volume hologram, and using an object beam and a divergent reference beam for said recording, (c) producing a real image of said real projection display screen of said primary volume hologram by illuminating said primary volume hologram with a reproduction beam, (d) producing a secondary volume hologram by recording said real image of said real projection display screen of said primary hologram as an object of said secondary volume hologram, wherein said real image is positioned in the plane of said secondary volume hologram, and (e) optically integrating said secondary volume hologram with said transparent carrier plate to form said holographic display screen as a see through holographic display screen.
