Abstract
A method and apparatus for checking luminescent value documents, in particular bank notes, with a luminescence sensor. The value document to be checked is irradiated to excite luminescence radiation, and the luminescence radiation emanating from the value document is detected with spectral resolution. Since the value document to be checked is transported past the luminescence sensor in the transport direction and is illuminated with an illumination area which extends in the transport direction, an effective measurement is possible even of value documents that emit very little luminescence radiation.
