Abstract
(EN)
A light detection and ranging device according to one embodiment comprises: a light transmitting unit for emitting a plurality of beams in different directions from each other; and a light receiving unit for allowing rear light beams, which return by being reflected after the emitted beams hit an object, to be incident at angles different from each other, and measuring information on the object by using the plurality of incident rear light beams, wherein the light transmitting unit comprises: at least one light source for emitting light; a beam splitting unit for splitting the light emitted from the at least one light source into a first beam and a second beam; and a beam steering unit for dividing, into a plurality of third beams, the second beam split by the beam splitting unit such that the third beams are emitted in directions different from each other, wherein the plurality of beams emitted from the light transmitting unit include the first beam and the plurality of third beams.
