Abstract
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, includes a detection device for spectrally resolved detection of the detection radiation and emission of detection signals which represent at least one property of the 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 and which has a spectrum with a structure which is within the spectral detection range, and which has a radiation source which acts as the transmitter of a light barrier or of a light scanner by means of which barrier or scanner a motion and/or a position of the value document relative to the capture area is capturable, and a control/evaluation device which is configured for receiving detection signals from the detection device, evaluating them and emitting evaluation signals in dependence on the result of the evaluation, and which is further configured for employing detection signals which represent the property of the reference radiation, for checking and/or for adjusting the det…
