Abstract
The invention relates to a device for scanning an object using a scanning beam which is directed into a rotating deflector and which is diverted onto the object at a controllable diversion angle using a diverting unit that is arranged in a moveable manner. The diversion angle of the diverting unit is adjusted according to the centrifugal force acting upon said diverting unit and according to the rotational speed of the deflector.
Claims20
An apparatus for scanning objects with a scanning beam which comprises:
- a rotating diverter unit for the deflection of a scanning beam, which is incident axially to a rotational axis of the rotating diverter unit onto a movable deflector unit arranged outside the rotational axis, for deflecting the scanning beam at a controllable deflection angle onto an object, and wherein the movable deflector unit is arranged in such a way that the deflection angle of the movable deflector unit is adjusted as a function of the centrifugal force acting on the movable deflector unit and therefore as a function of the speed of the rotating diverter unit.
A process for scanning objects with a scanning beam, which comprises:
- deflecting a scanning beam with a rotating diverter unit where the scanning beam is incident axially to a rotational axis of the rotating diverter unit onto a movable deflector unit arranged outside the rotational axis, for deflecting the scanning beam at a controllable deflection angle onto an object;
- and
- arranging the movable deflector unit in such a way that the deflection angle of the movable deflector unit is adjusted as a function of the centrifugal force acting on the movable deflector unit and therefore as a function of the speed of the diverter unit.
