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.

A light source comprising a plurality of light emitting elements in a surface,
- wherein 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 each other, 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.
A light source comprising a plurality of surface light emitting elements,
- wherein an arrangement of the plurality of surface light emitting elements is such that an element interval in which irradiation light beams of at least adjacent surface light emitting elements of the plurality of surface light emitting elements overlap, and that the element interval is set in such a manner that a speckle pattern in an irradiated area of the irradiation light beams differs for each of the irradiation light beams.
