The utility model discloses a laser radar, which comprises a shell, and a light emitting assembly, a Powell prism, a beam splitter, a converging lens and a light receiving assembly which are arranged in the shell, and is characterized in that the light emitting assembly is used for emitting a detection light beam; the Powell prism is used for converging and processing the detection light beam into a linear light beam; the beam splitter is used for splitting the linear light beam from the Powell prism into at least two parallel linear light beams; the converging lens is used for converging reflected light obtained after the at least two parallel linear light beams meet a target to the light receiving assembly; and the light receiving assembly is used for receiving the reflected light converged by the converging lens. The beam splitter is additionally arranged behind the Powell prism, so that a linear light beam emitted by the Powell prism is divided into at least two parallel linear light beams in the vertical
