[Solution] This distance measurement device is configured to be provided with: a light projection unit that includes a light emission unit and that performs rotary scanning using projection light; a light reception unit; a distance measurement unit that measures the distance to an object to be measured, on the basis of emission of the projection light and light reception performed by the light reception unit; and an emission control unit that controls the light emission unit, wherein, for every n cycles (n is an integer of 1 or greater) of the rotary scanning, the emission control unit changesthe output level of the projection light and the emission interval of the projection light, while keeping the average power of the projection light fixed.

    本发明作为一种距离测定装置,具备:投光部,其包括发光部并进行基于投射光的旋转扫描;受光部;距离测量部,其基于上述投射光的射出和上述受光部的受光来测量到测量对象物的距离;以及发光控制部,其控制上述发光部,上述发光控制部对上述旋转扫描的n个周期(n为1以上的整数)中的每个周期,将上述投射光的平均功率设为恒定并使上述投射光的输出电平以及上述投射光的发光间隔变化。
