Abstract: A light-emitting device includes: a light source including plural light-emitting elements; a first optical member that is provided in a light-emitting path of the light source, the first optical member being configured to narrow a spread angle of light emitted from each of the light-emitting elements of the light source and emit the narrowed light; and a second optical member that is provided on a light-emitting side of the first optical member and is configured to diffuse and irradiate light incident from the first optical member.

Abstract: A light emitting device includes: a light emitting part having multiple light emitting regions arranged along a first direction; and an optical system that is disposed on a light-exit side of the light emitting part and that deflects light emitted from the multiple light emitting regions in different directions, the optical system being configured such that a light exit angle in a second direction, which intersects the first direction, is smaller than the light exit angle in the first direction.

Abstract: An optical distance-measuring device includes: a light emitter having plural light-emitting areas that are arrayed in a first direction; an optical system provided at a position toward which the light emitter emits light, the optical system causing light beams respectively emitted from the plural light-emitting areas to be deflected in respectively different directions; and a detector including plural detecting elements configured to detect a reflection of light outgoing from the optical system. Detecting directions of some of the plural detecting elements are different from detecting directions of others of the plural detecting elements in the first direction.
