Abstract
A system for improving the visibility in vehicles, including the following: an illumination optical system ( ) for continuous radiation of infrared pulsed light; an associated receiver optical system ( ) for receiving reflected components of the radiated light; a display ( ) for representing information obtained by the receiver optical system ( ), and a device ( ) for determining the presence of glare in the receiver optical system ( ) from a foreign vehicle illumination optical system and for changing the keying interval or duty cycle of the infrared pulsed light of the illumination optical system ( ) driven with fixed keying interval in dependence upon the vehicle direction of travel in such a manner that the glare is eliminated. Therein the illumination optical system is driven is driven with a fixed keying interval depending upon the vehicle direction of travel or, in certain cases, the direction of illumination. In an alternative embodiment, the illumination optical system ( ) is operated at a wavelength which depends upon the vehicle direction of travel or, in certain cases, the direction of illumination.
