Abstract
Reliability of an in-vehicle headlight is improved by changing a light distribution pattern without using any mechanical configuration. The in-vehicle headlight includes a laser light source, a spatial light modulator, a spatial-light-modulator controller, and a projection lens. The laser light sourceemits a laser light beam. The spatial light modulatormodulates a phase distribution of the laser light beamemitted by the laser light source. The spatial-light-modulator controller is provided in a headlight controller, and controls the spatial light modulator. The spatial-light-modulator controller controls the spatial light modulatorso as to modulate the phase distribution of the laser light beam, and changes the light distribution pattern projected from the projection lens
