Abstract (en)
[origin: EP1170707A2] A focussing lens (2,3) converts a bundle of rays emitted by a radiation source (1) so that the surface of an object (5) being examined picks up a scanning bar (22) for making part of an identifying feature (21) on the object become luminescent. The luminescent signal generated by this passes via a detecting lens (9,9') to an evaluating device.
