Abstract
A laser survey instrument includes a laser source; a beam waist position varying optical system having a movable lens group through which a laser beam emitted from the laser source passes, so that the movement of the movable lens group in an optical axis direction causes the beam waist position of the laser beam to vary; a rotatable head portion from which the laser beam transmitted through the beam waist position varying optical system is emitted; a reciprocating-scan angle setting device for setting a reciprocating-scan angle of the rotatable head portion in accordance with position data of the movable lens group of the beam waist position varying optical system; and a head portion controller for reciprocally moving the head portion by the reciprocating-scan angle.
