PROBLEM TO BE SOLVED: To realize an on-vehicle illuminator which has a configuration of using a laser light source for a light source part and is capable of easily adjusting illuminance patterns.SOLUTION: An on-vehicle illuminator of this invention comprises a light source part including a laser light source, a plurality of hologram elements into which laser light emitted from the laser light source is entered, and a control part that controls the strength of laser light. At least a part of the plurality of hologram elements have mutually different pieces of information recorded, which reproduce patterns with mutually different illuminances on incidence of laser light. The control part controls the strength of laser light entered into each of the plurality of hologram elements, thereby enabling a change in synthetic illuminance patterns reproduced into an irradiation target region by the synthesis of illuminance patterns.SELECTED DRAWING: Figure 4

    【課題】レーザ光源を光源部に用いる構成であって、照度パターンを容易に調整することのできる車載用照明装置を実現する。【解決手段】 本発明の車載用照明装置は、レーザ光源を含む光源部と、光源部から放射されたレーザ光が入射される複数のホログラム素子と、レーザ光の強度を制御する制御部とを備える。少なくとも一部の複数のホログラム素子は、相互に異なる情報が記録されており、レーザ光が入射されることで照射対象領域に相互に異なる照度パターンを再生する。そして、複数のホログラム素子のそれぞれに対して入射されるレーザ光の強度を制御部が制御することで、照度パターンが合成されて照射対象領域に再生される合成照度パターンの変更が可能な構成である。【選択図】 図4
