Abstract

Apparatus for marking and/or scanning (m/s) an object comprising a m/s head (20) having a plurality of receiving spaces (24) for m/s devices (40), a driving mechanism for moving the object, a measuring device (50) for measuring the object speed comprising a transmitter having a transmitting fibre (56) for transmitting light to the object, a receiver having first and second light receiving fibres (57, 58) for receiving light reflected from the object forming light signals, and processor means (70) for determining a time shift between the light signals to provide a speed value of the object, all the fibres are arranged in a common first ferrule (52), the m/s devices include second ferrules, the first and second ferrules have corresponding connector sections and are variably connected to the receiving spaces of the scanning head, and the speed measuring device is arranged in one of the receiving spaces. The invention further relates to a method for measuring the object speed with the m/s apparatus.
