The second aperture plate is disposed in a light path of the monitoring light beam and includes a second aperture that shapes a beam diameter of the monitoring light beam. The photodiode receives the monitoring light beam.

摘要： 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.

摘要： A deflecting unit deflects a plurality of light fluxes from a light source including a plurality of light emitting elements arranged in two-dimensional array. An coupling optical system between the light source and the deflecting unit includes an optical coupling element that collimates the light fluxes and a line-imaging element that images the light fluxes near the deflecting unit in a sub-scanning direction. A holding unit holds the line-imaging element in a state that a position of the line-imaging element is adjusted with respect to a direction parallel to the sub-scanning direction. A scanning optical system condenses the deflected light fluxes on the scanning surface.
