More Information
Summary:A 3D scanner for recording the 3D topography of an object, the 3D scanner including: a projector unit configured for projecting a structured beam of probe light onto the object; an imaging unit arranged to acquire 2D images of the object when the object is illuminated by the structured probe light beam; and an actuator unit arranged to control the position of the structured probe light beam at the object by rotating a movable portion of the projector unit around a pivoting axis, the actuator unit including a rotation motor including or arranged to drive a wheel, where the surface of the wheel operatively coupled to the movable portion of the projector unit has a radial distance from the axis of the rotation motor which changes with the rotation.
