Device for improving visibility in vehicles
First Claim
1. A device for improving visibility in a vehicle having one or more laser headlights radiating laser light outside the visible spectrum into a predetermined solid area angle ahead of the vehicle, comprising:
- a first laser headlight radiating first laser light into a first part of the predetermined solid angle area ahead of the vehicle, the first laser light having a wavelength outside the visible spectrum, a second laser headlight radiating second laser light into another part of the predetermined solid angle area ahead of the vehicle, the second laser light having a wavelength outside the visible spectrum, a camera sensitive to light outside the visible spectrum for taking images of current traffic scenes; and
an optical display system in the vehicle for reproducing the captured images in the visible spectrum.

Abstract
The present invention relates to a device for improving visibility in a vehicle, especially in darkness, bad weather and fog, including one or more laser headlights radiating laser light of a wavelength outside the visible spectrum into a predetermined solid angle area ahead of the vehicle, a camera which is sensitive outside the visible spectrum and used for taking images of current traffic scenes, as well as an optical display system in the vehicle for reproducing the captured images in the visible spectrum. According to the present invention, provision is made for at least two different types of laser headlights which each illuminate different parts of the solid angle area to be observed to produce an angle-dependent radiation pattern of the laser light in a simple manner.
