Abstract
An optical transmission assembly for transmitting a source image includes a waveguide assembly, an incoupling assembly for coupling light emitted from the source image into the waveguide assembly, and an outcoupling assembly for coupling the light guided in the waveguide assembly out of the waveguide assembly. The light emitted from the source image and coupled into the waveguide assembly can be propagated between the incoupling assembly and the outcoupling assembly in the waveguide assembly by means of a total reflection. The incoupling assembly has at least one diffractive incoupling grating which is inclined by an angle (α) ranging from 20° to 60° relative to a normal of a boundary surface of the waveguide assembly, and/or the outcoupling assembly has at least one diffractive outcoupling grating which is inclined by an angle (α) ranging from 20° to 60° relative to a normal of a boundary surface of the waveguide assembly.
