<P>PROBLEM TO BE SOLVED: To provide a laser radar device capable of carrying out detection around the device as well as three-dimensional detection. <P>SOLUTION: The laser radar device with a laser diode 10 and a photodiode 20 includes: a rotation deflection mechanism 40 with a deflection section 41 configured to be rotatable around a predetermined central axis 42a, for deflecting a laser beam towards a space by the deflection section 41 and deflecting reflection light toward the photodiode 20; and a motor 50 for rotationally driving the rotation deflection mechanism 40. The laser radar device also includes a motor 70 for rotating the laser diode 10 and a control circuit 80 for controlling the motor 70. The incident direction of the laser beam incident on the deflection section 41 is changed by rotating the laser diode 10 by the motor 70, and the orientation of the laser beam from the deflection section 41 is changed with regard to the direction of the central axis 42a. <P>COPYRIGHT: (C)2013,JPO&INPIT |
