Abstract
A light scanning apparatus includes a light source configured to output laser light, and a mirror configured to reflect the laser light from the light source. The light scanning apparatus includes a mirror driving unit configured to resonantly drive the mirror in a first direction and non-resonantly drive the mirror in a second direction, the second direction being perpendicular to the first direction. The light scanning apparatus includes a first sensor configured to output a signal in accordance with a first deflection angle at which the mirror is oriented with respect to the first direction. The light scanning apparatus includes a second sensor configured to output a signal in accordance with a second deflection angle at which the mirror is oriented with respect to the second direction.
