To provide an illumination device, a hologram element, and a vehicle control method capable of optimizing a lighting mode in an illuminated zone with a simple configuration.SOLUTION: An illumination apparatus that illuminates an illuminated zone 4 having a first direction and a second direction crossing the first direction includes a light source 2 to emit a coherent light beam, and a diffraction optical element 3 to diffract the coherent light beam incident from the light source. The diffraction optical element 3 diffracts the incident coherent light beam so that width of the illuminated zone 4 in the second direction gradually becomes wider along the first direction of the illuminated zone 4 from a nearer side to the diffraction optical element 3.SELECTED DRAWING: Figure 1

    【課題】簡易な構成で被照明領域の照明態様を最適化できる照明装置、ホログラム素子および車両制御方法を提供する。【解決手段】第1の方向および第1の方向と交わる第2の方向を有する被照明領域4を照明する照明装置であって、コヒーレント光を放射する光源2と、光源から入射されたコヒーレント光を回折させる回折光学素子3と、を備える。回折光学素子3は、被照明領域4の第2の方向の幅が回折光学素子3により近い側から被照明領域4の第1の方向に沿って漸次に広がるように、入射されたコヒーレント光を回折させる。【選択図】図1
