Abstract
Provided is a vehicular headlight that is capable of generating a clear light distribution pattern using a monolithic array light source of surface emitting lasers. The vehicular headlight 1a includes a VCSEL array 5, an image generation unit including a lens array 6 which outputs incident light from the VCSEL array 5 as collimated light so that an image of a light distribution pattern as an illuminance distribution is generated on an output side, a light distribution pattern forming unit 7 having an image forming surface on which the image is formed by the incident light from the image generation unit, and a projection unit 8 outputting the incident light from the light distribution pattern forming unit to an irradiation region in front of the vehicle.
