Abstract:
1. A sensor device for spectrally resolved capture of optical detection radiation which emanates from a value document transported through a capture area of the sensor device in a predefined transport direction, comprising: a detection device configured to detect spectrally resolved detection radiation in at least one predefined spectral detection range and to output detection signals which represent at least one property of the detected detection radiation; at least one reference radiation device which emits optical reference radiation which is coupled into a detection beam path of the detection device at least partly in dependence on the position of a value document relative to the capture area, and which has a spectrum with at least one narrow band which is within the predefined spectral detection range, and/or a spectrum with at least one edge which is within the predefined spectral detection range, and which is detected by the detection device so that said detection signals also represent at least one property of the reference radiation; and a control and evaluation device configured to use a part of the detection signals which represent at least one property of the reference radiation to check and/or adjust the detection device and/or to evaluate a part of the detection signals which represent the at least one property of detection radiation emanating from a value document.
