LASER OPTICAL DEVICE AND IMAGE PROJECTION DEVICE

摘要

A laser optical device is provided with: a plurality of laser light sources (1A) and (1B); a collimating lens (2) for collimating the lights emitted from each of the plurality of laser light sources (1A) and (1B), the collimating lens (2) having, in plan view from the direction perpendicular to both the optical axis and a line connecting the plurality of laser light sources (1A) and (1B), an optical axis intersecting with the line; and a deflecting element (3) for deflecting a plurality of lights (L2A) and (L2B) emitted from the collimating lens (2) so that output lights obtained by optical processing of the lights emitted from each of the plurality of laser light sources (1A) and (1B) are adjacent.
