In described examples of a headlamp to project a beam of light from a lens, the headlamp includes: an illumination module to output a light beam to an illumination path; and illumination optics to receive the light beam and to provide illumination to a programmable spatial light modulator. The programmable spatial light modulator is arranged to receive the illumination and to output non-uniform illumination as patterned light to projection optics. The projection optics are arranged to receive the patterned light and to output the patterned light through the lens. At least one of the illumination optics and the projection optics includes an anamorphic lens to shape the light beam.
