Patent attributes
A laser radar according to an embodiment of the invention includes a beam irradiation head which emits a laser beam and a control circuit which controls the beam irradiation head to perform scan in a two-dimensional direction with the laser beam. In the laser radar, the beam irradiation head includes a laser beam source; a mirror to which the laser beam emitted from the laser beam source is incident; and a driving mechanism which rotates the mirror in first and second directions about a first rotating axis and a second rotating axis perpendicular to the first rotating axis respectively. The control circuit controls the rotation of the mirror in the first direction and the second direction such that a scan region of the laser beam becomes a rectangular shape.
