Device and method for producing an edge-lit-hologram, edge-lit-hologram and lighting device for a vehicle

A device for producing an edge-lit-hologram, the device comprising:

• a light source or a laser light source to generate a light beam;
• an optical splitter to split the light beam generated by the light source into an object beam and a reference beam;
• an imprinter to imprint, to the object beam, computer-generated information pertaining to the edge-lit-hologram;
• and
• optics for overlapping the object beam and the reference beam on or in a photosensitive recording medium for imprinting the edge-lit-hologram,
• wherein the optics comprise at least one transparent body through which the reference beam enters the photosensitive recording medium during operation of the device,
• wherein the at least one transparent body is shaped and disposed in the device such that the reference beam enters the at least one transparent body at an angle of less than 10° to the normal on a surface of the at least one transparent body or enters the at least one transparent body perpendicular to the surface of the at least one transparent body, and
• wherein the device further comprises a transparent substrate on which the photosensitive recording medium is disposed, the transparent substrate being positioned between the at least one transparent body and the photosensitive recording medium.
