Abstract:
1. A system mountable in a vehicle, the system for classifying a light source, the system comprising: a spatial image sensor with a portion that defines a plane; a lens disposed between the light source and the spatial image sensor, that is adapted to provide an image of the light source on said spatial image sensor; a diffraction grating or prism disposed between said lens and said light source, that is adapted to direct a spectrum of the light source onto said spatial image sensor in a direction having a vertical component in the plane of said image sensor that tends to position said spectrum at a location on the spatial image sensor that corresponds to sky; and a processor operatively connectible to said spatial light sensor, wherein said processor is configured to locate said spectrum in the plane of said spatial image sensor and to use said spectrum to classify said light source as belonging to a class selected from a plurality of classes of light sources expected to be found in a vicinity of the vehicle.
