Abstract

The invention relates to a device for representing optical information by means of a virtual image (P), in particular in a motor vehicle. The optical information is in the form of light beams extending from an image generating device (1), over at least one optical element to a surface and the virtual image is visible in front of, behind or in said surface. The light beams produce a beam path. Said invention is characterised in that an optical element (4), which influences beams, is arranged in the beam path between the image generating device (1, 2, 3) and the surface (WS), and that the optical element (4), which influences the beams, is arranged in the position thereof such that it can be modified by means of an adjusting device (5).
