摘要：An optical scanning apparatus, an image projecting apparatus, and a mobile
object. The optical scanning apparatus (10) includes a light source (12) configured to emitlight, a light deflector (13) configured to deflect the light emitted from the light sourceat least in a sub-scanning direction to perform optical scanning on a scan region (15), alight receiver (18) configured to receive, within a predetermined range in the sub-scanning direction, the light used for optical scanning performed by the light deflector(13), and a controller (11) configured to control the light deflector (13) based on thenumber of times of light reception of the light receiver at a plurality of positions in thesub-scanning direction within the predetermined range. The image projecting apparatus(500) includes the optical scanning apparatus (10), and a projection optical system (511)configured to project light emitted from the optical scanning apparatus (10) to the scanregion (15). The light deflector (13) of the optical scanning apparatus (10) in the imageprojecting apparatus (500) scans, with light that is modulated based on imageinformation, the scan region (15) to project an image. The mobile object (400, 701)includes the optical scanning apparatus (10) or the image projecting apparatus (500).
