Patent ID: 7880865

Claim:
A laser radar apparatus comprising: a laser beam generator that generates a laser beam; an optical detector that detects reflected light that has been reflected from a field to be observed; a deflection member that has a surface deflecting the laser beam toward the field and deflection the reflected light toward the optical detector; a support member that has a central axis, supports the deflection member, and is rotatable on the central axis; a drive means that drives the support member so that the support member is rotated on the central axis; changing means that changes an incidence direction of the laser beam onto the deflection member relatively to the surface of the deflection member so that the laser beam deflected from the deflection member is scanned in a direction along the central axis; and control means that controls the changing means so as to allow the laser beam deflected from the deflection member to scan the field in the direction at all rotated positions of the support member.
