Abstract
The invention concerns a process for improving the view in vehicles, in particular at night, poor weather and fog, in which laser light is emitted at a wavelength outside the visible spectrum in a predetermined angular range, which is being observed with a camera, of which the images are provided to the vehicle operator. The laser light is emitted essentially continuously only when the headlights of the vehicle are in operation and/or when the vehicle is in motion. In this manner the vision of other traffic participants is ensured in a particularly simple manner.
