Abstract
Disclosed is an image generator with several pixels, from which light bundles are emitted for generating an image, a control unit for controlling the image generator and an imaging optical system which comprises a light guiding element with a front side and a rear side, which light guiding element has an input grating formed on the front or rear side and an output grating formed on the front or rear side. The light bundles are input into the light guiding element by means of diffraction at the input grating, guided in the light guiding element by means of total internal reflection up to the output grating and output by means of diffraction at the output grating such that a user can perceive the generated image.
