To provide an optical scanner, a display system, and a movable body that reduce the influence of radiation light outside an image area.SOLUTION: There is provided an optical scanner comprises a light deflection unit 13 that scans radiation light radiated from a light source 11 in a first scanning direction and a second scanning direction orthogonal to the first scanning direction, in an image area 15R1 included in a scanning range 15R3 where the light deflection unit 13 scans the radiation light, turns on the light source 11 to form an image based on image information, and turns on the light source 11 when the light deflection unit 13 scans a detection area 61 outside the image area 15R1, comprises a light detection unit 61 that detects the radiation light when the light deflection unit 13 scans the detection area 61, and is provided with a blocking area 74 for blocking the radiation light scanned by the light deflection unit 13 between the image area 15R1 and the detection area 61. Also provided are a display system and a movable body.SELECTED DRAWING: Figure 16
【課題】画像領域外における照射光の影響を低減する光走査装置、表示システム、移動体を提供する。【解決手段】光源11から照射される照射光を、第1走査方向と、第1走査方向に直交する第2走査方向とに走査する光偏向部13を備え、光偏向部13が照射光を走査する走査範囲15R3に含まれる画像領域15R1内で、画像情報に基づき光源11を点灯させて画像を形成するとともに、光偏向部13が画像領域15R1外の検知領域61を走査するときに光源11を点灯させ、光偏向部13が検知領域61を走査するときに、照射光を検知する光検知部61を備え、画像領域15R1と検知領域61の間における光偏向部13が走査する照射光を遮蔽する遮蔽領域74を設けた光走査装置、表示システム、移動体である。【選択図】図16
