Abstract

An apparatus for marking an object includes a marking unit for marking the object with a laser beam, a transporting device for transporting the object and a device for determination of a position of the object by means of ultrasonic waves originating from the object. A pulsed laser beam is directed to the object to cause vibrations at a surface of the object, by which vibrations the object is excited to generate ultrasonic waves.
