Abstract
A system for optically stabilizing the projection light from a vehicle. The system includes a light source for generating and emitting light, an aperture, and a spatial light modulator for altering an illumination pattern of the light. The spatial light modulator disposed along an optical path extending from the light source to the aperture, wherein the light projects from the aperture. The system also includes an inertial-sensing. The inertial-sensing unit generates signals representing a position of the vehicle, an orientation of the vehicle, or both. The system further includes a control unit. The control unit receives signals from the inertial-sensing unit to determine changes in position and/or orientation of the vehicle relative to the road and sends signals to the spatial light modulator adjust an illumination pattern of the light to steer the light to a nominal value, defined by a vehicle in a level plane relative to a road system.
