To provide an optical scanner which reduces an influence of irradiation light detected by a light detection unit, a display system device, and a moving body.SOLUTION: The optical scanner comprises a light source 11, a light deflection unit 13 scanning irradiation light irradiated from the light source in a first scanning direction and a second scanning direction crossing the first scanning direction, a control unit 175 lighting the light source for a predetermined period, and a light detection unit for detecting the irradiation light in the predetermined period. The predetermined period includes a point of time at which the light deflection unit makes a scanning direction turn back in the first scanning direction or the second scanning direction.SELECTED DRAWING: Figure 18

    【課題】光検知部により検知される照射光の影響を低減する光走査装置、表示システム装置および移動体を提供すること。【解決手段】光源11と、前記光源から照射される照射光を、第1走査方向と、前記第1走査方向に交差する第2走査方向とに走査する光偏向部13と、所定期間、前記光源を点灯させる制御部175と、前記所定期間における前記照射光を検知する光検知部と、を備え、前記所定期間は、前記光偏向部が、前記第1走査方向または前記第2走査方向において走査方向を折り返すタイミングを含むことを特徴とする。【選択図】図18
