Patent ID: 10884106

Abstract:
A light detection and ranging apparatus according to one embodiment includes a light transmitting unit for emitting a plurality of beams in different directions from each other and a light receiving unit for allowing backward-propagating lights returning after the emitted beams hit an object and are reflected from the object, to be incident at angles different from each other, and measuring information on the object by using the plurality of incident backward-propagating light, wherein the light transmitting unit includes at least one light source for emitting light; a beam splitter 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 the second beam split by the beam splitter into a plurality of third beams and for emitting the divided third beams 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.
