Abstract:
A two-dimensional scanning projector causing a light beam to scan in a first direction and a second direction orthogonal to the first direction, comprising: a first deflector which deflects the light beam in the first direction; and a scanning optical system arranged between the first deflector and a scanned surface, wherein the first deflector is arranged such that a rotation axis of the first deflector is inclined, in a plane including an optical axis of the scanning optical system and the second direction, by a first angle with respect to the second direction, and the light beam is incident on the first deflector such that, in the plane including the optical axis and the second direction, a chief ray of the light beam entering a center of a projected image is obliquely incident on the first deflector to form a second angle with respect to the optical axis.
