Abstract: A transparent holographic display screen for laser projection of at least one or more monochromatic wavelengths, is constructed to selectively diffuse an incident narrow-band laser beam at a predetermined solid angle and simultaneously to pass wide-band ambient light unobstructed through the display screen. The transparent holographic display screen has at least one holographic volume phase grating which is optically coupled to or integrated with a transparent carrier plate. The holographic display screen with its volume grating is produced by illuminating a real screen as an object into a primary hologram and recording a real holographic image of said real screen into a secondary hologram.

Abstract: The invention relates to a holographic display screen for laser projection of at least one or more laser wavelengths, which selectively diffuses the incident narrow-band laser beam at a predetermined solid angle and simultaneously lets the wide-band ambient light through unobstructed. Said display screen has at least one holographic phase grid which is optically coupled to a transparent backing plate. The invention also relates to methods for the production and the use of said device.
