An optical scanner, a display system, and a mobile object. The optical scanner includes a light source to emit irradiation light, a light deflector to scan the irradiation light emitted from the light source in a first scanning direction and in a second scanning direction intersecting with the first scanning direction, circuitry to turn on the light source for a predetermined length of time, and a photodetector to detect the irradiation light for the predetermined length of time. The predetermined length of time includes a timing at which the light deflector turns a scanning direction in the first scanning direction or the second scanning direction. The display system includes the optical scanner, a divergent part through which the irradiation light scanned by the light deflector is projected and diverges, and an imaging optical system to reflect projection light projected through the divergent part.
