Dynamic control of projected light relative to a scene
First Claim
1. A system for dynamically controlling illumination of a scene, the system comprising:
- an illumination unit coupled to a vehicle, the illumination unit comprising;
a light source positioned within a housing, anda spatial light modulator disposed along an optical path extending from the light source to an aperture, wherein the spatial light modulator creates an illumination pattern for light projected from the light source through the aperture along an axis of projection,an inertial-sensing unit coupled to the vehicle generating signals representing a measured inertial change of the vehicle in any direction; and
a control unit in communication with the illumination unit and the inertial-sensing unit, the control unit receiving the signals from the inertial-sensing unit and controlling the spatial light modulator based on the received signals from the inertial-sensing unit, wherein controlling the spatial light modulator comprises altering an operational state of the spatial light modulator to adjust an orientation of projection of the light along the axis of projection, the illumination pattern for the light, or combinations thereof.

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.
