<P>PROBLEM TO BE SOLVED: To provide a laser radar apparatus capable of controlling a scan period as necessary. <P>SOLUTION: Whether a short-distance target exists or not is determined (S150), and when the short-distance target exists (S150: YES), a distance measurement time factor is changed and set (S160). Concretely, a "light emission interval" to be a laser beam emission interval is made shorter than a usual light emission interval, and the "light receiving frequency" of reflected light beams from the same investigation area is to be reduced. Then, distance measurement is performed by the set distance measurement time factor (S100), a position of the target is acquired (S110), a speed of the target is calculated (S120), and data is updated (S130). Namely, laser beams are applied to the investigation area in parallel by using an immovable light distribution box and the emission interval of laser beams and the light receiving frequency of reflected light beams are changed to change time required for investigation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
