DEVICE AND METHOD FOR PRODUCING AN EDGE-LIT-HOLOGRAM, EDGE-LIT-HOLOGRAM AND LIGHTING DEVICE FOR A VEHICLE

摘要

A device for producing an edge-lit-hologram having a light source, in particular a laser light source, for generating a light beam, optical splitter for splitting the light beam generated by the light source into an object beam and a reference beam, imprinter for imprinting computer-generated information pertaining to the edge-lit-hologram to the object, 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 body transparent to the reference beam through which the reference beam enters the photosensitive recording medium during operation of the device. The at least one transparent body shaped and disposed in the device such that the reference beam enters the body at an angle of less than 10° to the normal on the surface of the body or enters the body perpendicular to the surface of the body.
