摘要：An apparatus and corresponding method for examining document having atleast one excitation device for exciting luminescence light in or on a document to beexamined and at least two detector units for detecting at least part of the luminescence
light emitted by the document. To increase the reliability of examination of the spectralcharacteristic of the luminescence light, it is provided that the detector units aredisposed one behind the other with respect to the luminescence light emitted by thedocument. This causes the luminescence light to successively hit the detector units andbe detected thereby. The apparatus and method permit any parallactic errors, whichoccur particularly with a laterally shifted arrangement of detector units, to be greatlyreduced so that the detector units can detect the luminescence light emitted by acommon partial spatial area of the document.
