The device includes a measuring graduation, which is connected to one of the two objects, as well as at least one scanning system for scanning the measuring graduation, which is connected to the other of the two objects. The scanning system is arranged to permit a simultaneous determination of the position values along at least one lateral and along one vertical shift direction of the objects.
