Abstract: The present invention is configured to make a wavelength (that is, a first wavelength) of light emitted from a first light source unit and a wavelength (that is, a second wavelength) of light emitted from a second light source unit different from each other, send the light of the first wavelength and the light of the second wavelength to the outside of a light detection and ranging (LIDAR) apparatus, detect the first wavelength reflected and returned by an object positioned outside the LIDAR apparatus by a first light detecting unit, and detect the second wavelength reflected and returned by an object positioned outside the LIDAR apparatus by a second light detecting unit, and may thus simultaneously detect an object positioned at a long distance and an object positioned at a short distance.

Abstract: The present invention relates to a lidar device for measuring a distance of an external object using light. According to the present invention, the transmission mirror and the reception mirror are integrally formed, and a shadow region, which has not been conventionally used, is utilized as a light transmission region such that a separate light transmission space is unnecessary, thereby enabling a minimized design of the lidar device.

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.
