PROBLEM TO BE SOLVED: To provide an optical device which has a function to suppress illumination to an oncoming vehicle with high convenience.SOLUTION: An optical device 100 is mounted in a vehicle 200 so as to illuminate a road surface. The optical device includes: a laser beam source which emits a laser beam; a scanning section which reflects the laser beam emitted from the laser beam source and emits scanning light; an optical element which receives the scanning light and emits light to the road surface so as to perform illumination; an imaging section which captures the situation of the vehicle periphery; and a determination section which analyzes the images captured by the imaging section and determines whether or not a characteristic structure section exists. When the determination section determines that the characteristic structure section exists, irradiation to the characteristic structure section is suppressed or emphasized.SELECTED DRAWING: Figure 9

    【課題】対向車に対する照明を抑制する機能を有し、利便性が高い光学装置を提供する。【解決手段】車両200に搭載され、路面を照明する光学装置100であって、レーザー光を射出するレーザー光源と、前記レーザー光源から射出されたレーザー光を反射し、走査光を射出する走査部と、前記走査光が入射され、路面に光を出射することで照明を行う光学素子と、車両周辺の様子を撮像する撮像部と、前記撮像部で撮像した画像を解析し特徴的構造部が存在するかを判定する判定部と、を有する。判定部で特徴的構造部が存在すると判定すると、特徴的構造部への照射を抑制するか又は強調する。【選択図】図9
