Abstract: A distance measurement apparatus includes a light emitting unit that has plural light emitting elements, and is able to be driven independently in plural regions, a light receiving unit provided with plural light receiving elements that receive reflected light of light applied to an object from the light emitting unit, a shaping unit that causes an overlapping portion to be generated in which light reception of the reflected light overlaps in the adjacent regions, on the light receiving unit, a measurement unit that measures a distance to the object, from a difference between a waveform of light received by the light receiving unit and a waveform of light emitted by the light emitting unit, and a correction unit that corrects a distance difference in the reflected light in the adjacent regions, by using a distance measurement value in the overlapping portion measured by the measurement unit.

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.
