Title:
LIGHT-EMITTING ELEMENT ARRAY AND OPTICAL MEASUREMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/003660
Kind Code:
A1
Abstract:
A light-emitting element array provided with a light-emitting element group including a plurality of light-emitting elements, and a plurality of lenses which are provided on the output surface side of the plurality of light-emitting elements and in correspondence to the plurality of light-emitting elements, and which deflect light from the plurality of light-emitting elements on the basis of a positional relationship with the plurality of light-emitting elements. From the center of the light-emitting element group toward the end side thereof, the distance between the light-emitting central axis of the plurality of light-emitting elements and the central axis of the plurality of lenses corresponding to the plurality of light-emitting elements becomes greater and the degree of change in distance becomes smaller.
