Object e.g. bank note, receiving and verifying method, involves adjusting intensity of illumination of rear side such that partial area illuminated by source from front side has intensity that is same as that of remaining surfaces of object

摘要

The method involves illuminating a surface of an object (1) with radiation e.g. infrared radiation, by a radiation source (3), where the object has an imprint (7) or a marking (2). The reflected radiation is received and evaluated by a receiving unit (4). A rear side and/or a translucent partial area (8) of the object is illuminated with an illuminating unit. Intensity of the illumination of the rear side is adjusted such that the partial area illuminated by the radiation source from a front side, has intensity that is same as remaining surfaces of the object. An independent claim is also included for a device for receiving and verification an object.
