Abstract: An optical device according to an embodiment of the present disclosure includes a light source in which a plurality of light emitting elements are arranged at a predetermined distance, an optical system configured to convert light beams from the plurality of light emitting elements into line light beams, and a light deflection element configured to deflect each of the line light beams. Each of the line light beams is caused to be incident on the light deflection element such that a longitudinal direction of each of the light beams is aligned with a direction of a rotating axis of the light deflection element.

Abstract: There is provided an improved light source including a plurality of light emitting elements in a surface. An arrangement of the plurality of light emitting elements fulfills, in an assumed projection area, an element interval at which irradiation light beams of the plurality of light emitting elements overlaps, and fulfills an element interval at which a speckle pattern of each of the irradiation light beams obtained in the assumed projection area is different for each of the irradiation light beams.

Abstract: According to one embodiment, a light source includes a plurality of light-emitting elements each including one or more surface-emitting lasers; and a plurality of detecting elements located on a same substrate as the light-emitting elements. The detecting elements individually detect quantities of output light of the light-emitting elements.
