Abstract

A lidar device for measuring distance according to the present invention comprises a laser output unit for outputting laser, and a sensor unit for acquiring the laser output by the laser unit, wherein the laser output unit comprises: a laser output array comprising a first laser output unit, a second laser output unit and a third laser output unit, each comprising one or more laser output elements; and a prism array for steering the laser output from the laser output array. The prism array comprises: a first prism element for steering the laser from the first laser output unit and second laser output unit; a second prism element for steering the laser from the third laser output unit; a third prism element for steering the laser from the first laser output unit and third laser output unit; and a fourth prism element for steering the laser from the second laser output unit. The distance between first and third locations on the third prism element is smaller than the distance between the first laser output unit and third laser output unit, the first location being the location on the third prism element from which the first laser from the first laser output unit is irradiated, and the third location being the location on the third prism element from which the third laser from the third laser output unit is irradiated.
