To provide an optical scanner, a display system, and a mobile object, which can suppress accuracy deterioration due to changes in an environment or changes over time.SOLUTION: An optical scanner, a display system, and a mobile object include an optical deflector 13 for scanning irradiation light emitted from a light source device 11 in a main scanning direction and a sub-scanning direction perpendicular to the main scanning direction, and a light-receiving element 61 for detecting the irradiation light when the optical deflector 13 scans a detection area, turns on the light source device 11 when the optical deflector 13 scans a scanning area 15R3, and moves the scanning area 15R3 between a position which is not overlapped with the detection area and a position which is overlapped with the detection area in the sub-scanning direction.SELECTED DRAWING: Figure 20
【課題】環境変化や経時等による精度低下を抑制できる光走査装置、表示システム、移動体を提供する。【解決手段】光源装置11から照射される照射光を、主走査方向と、主走査方向に直交する副走査方向とに走査する光偏向装置13と、光偏向装置13が検知領域を走査するときの照射光を検知する受光素子61と、を備え、光偏向装置13が走査領域15R3を走査するときに光源装置11を点灯させるとともに、副走査方向において、検知領域と重ならない位置と検知領域と重なる位置との間で走査領域15R3を移動させる光走査装置、表示システム、移動体である。【選択図】図20
