LASER RADAR DEVICE AND DETECTION METHOD

A scanning mirror unit (13) two-dimensionally scans with infrared laser light emitted from a first light source unit (Dir), visible laser light emitted from a second light source unit (Db, Dg, Dr), or laser light in which both the laser light are superimposed on each other. A reflected light detection unit (PD2) detects reflected light of infrared laser light emitted via the scanning mirror unit (13). An object recognition unit (22) recognizes an object present within the emission range (2) of infrared laser light based on the reflected light detected by the reflected light detection unit (PD2). When an object is recognized by the object recognition unit (22), the second light source unit (Db, Dg, Dr) emits visible laser light, which is different in accordance with information on the object, toward the object, a neighborhood of the object, or both the object and the neighborhood thereof.
