Zusammenfassung:	To suppress a rise in temperature regarding a light source device including a light emitting unit in which a plurality of light emitting elements of a vertical cavity surface emitting laser is arranged.SOLUTION: The light source device includes: a light emitting unit in which a plurality of light emitting elements of a vertical cavity surface emitting laser is arranged; and a drive unit for causing the plurality of light emitting elements to emit light within a light emission target period to perform time-division light emission within the light emission target period regarding the light emitting elements of the light emitting unit. By using time-division light emission, the number of light-emitting elements that emit light simultaneously can be reduced.SELECTED DRAWING: Figure 3 【課題】垂直共振器面発光レーザによる発光素子が複数配列された発光部を備える光源装置について、温度上昇の抑制を図る。【解決手段】本技術に係る光源装置は、垂直共振器面発光レーザによる発光素子が複数配列された発光部と、発光部における発光素子について、発光対象期間内に発光されるべき複数の発光素子を発光対象期間内において時分割発光させる駆動部とを備える。時分割発光とすることで、同時発光される発光素子の数が減少される。【選択図】図３
