Abstract: Provided is a LIDAR apparatus of emitting laser beam in a scanning scheme in each direction within a field of view and separately obtaining reflected light in each direction to calculate a distance up to a reflector. The LIDAR apparatus may rapidly and efficiently perform scanning, may be compact, may significantly decrease a required laser output as compared with an apparatus according to the related art simultaneously emitting laser in all directions within the field of view, may be manufactured at a low cost, and may be operated at a low cost.
