Abstract
A scanning apparatus for scanning a light beam includes a mirror configured to reflect an incident light beam, a motor configured to rotate the mirror to change a direction along which the light beam reflected by the mirror travels, and a detector configured to obtain a detection value corresponding to a tilt of a detected region of the mirror, with the detection value being changed in accordance with a rotation angle of the mirror. In addition, a processor is configured to obtain a tilt angle of the mirror based on the detection value obtained by the detector and the rotation angle of the mirror.
