A device for generating a virtual light image. The device includes a real light source, a curved retroreflector surface, and a semi-transparent mirror. The retroreflector surface is situated so that the light of the real light source transmitted through the semi-transparent mirror does not reach the retroreflector surface. A shape of the retroreflector surface for a given visibility range, at least in a subregion of the area that is essential for the image in the visibility range, is determined by the fact that at each point of the subregion, the pair of a reflection angle A and an optical distance between this point of the subregion of the retroreflector surface and the virtual light image is Pareto-minimal, provided that the subregion of the retroreflector surface does not interrupt primary beams from the real light source to the semi-transparent mirror.
