<p>A laser radar device (100) mounted on a vehicle includes a first laser emission part (R1-R4) configured to generate a measuring laser beam (L2) by using a laser beam (L0) emitted from a laser source (21) and to illuminate a predetermined area in a front traveling direction and a second laser emission part (R5, R6) configured to generate a measuring laser beam (L2) by using the laser beam (L0) emitted from the laser source (21). A beam spread angle (±), viewed from a side of the vehicle, of the measuring laser beam (L25, L26) generated by the second laser emission part (R5, R6) is larger than a beam spread angle (¸), viewed from a side of the vehicle, of the measuring laser beam (L21-L24) generated by the first laser emission part (R1-R4).</p> |
