Abstract
An automotive headlamp is provided that includes a digital micromirror device (DMD) headlight module, the DMD headlight module including a DMD, a white light module to provide a white light beam to illuminate the DMD, illumination optics optically coupled between the DMD and the white light module to prepare the white light beam for illuminating the DMD, and projection optics optically coupled to the DMD to receive pixelated light reflected by the DMD and project a pixelated light beam on road, in which at least one of the DMD, the white light module, and the illumination optics shape a beam profile of the white light beam such that the light reflected by the DMD has a pixelated non-uniform beam profile suitable for projecting a white light beam that forms a portion of a white light beam of the headlamp.
