Projector
A projector includes laser light sources which emit light, a mems mirror which operates at specified angles of deflection so as to scan light emitted from the laser light sources over a projection area at a sine-function angular velocity in which a scanning speed in a vicinity of a central portion of the projection area in a horizontal direction is faster than a scanning speed in a vicinity of end portions, and a first lens which is disposed at a position between the mems mirror and the projection area and which refracts light scanned by the scanner such that the scanning speed of the light scanned by the mems mirror in the vicinity of the central portion of the projection area in the horizontal direction is equal or substantially equal to the scanning speed in the vicinity of the end portions in the horizontal direction.. .
