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
