PROBLEM TO BE SOLVED: To provide an optical radar apparatus for emitting a laser beam at a desired angle in the rotation center axis direction of a rotated and driven polygon mirror without complicating the structure.SOLUTION: This optical radar apparatus includes an angle adjustment mechanism 52 for varying the tilt angle of an installation plate 46 on which the polygon mirror 42 is installed, and a clutch mechanism 50 for switching between transmission and non-transmission of a driving force from a motor 44 for rotating and driving the polygon mirror 42 to the angle adjustment mechanism 52. Thus, the tilt angle of the installation plate can be varied without disposing an exclusive drive source for varying the tilt angle of the installation plate 46. Thus, the position of the detection area in the vertical direction can be adjusted. |
