Device and method for calibrating a sensor system

Abstract

The invention relates to an apparatus and a method for the calibration of a sensor system. The invention starts out from an apparatus for the calibration of a sensor system, having at least one sensor and at least one excitation source, a control device for controlling the sensor system, a calibration medium and a drive which moves the calibration medium, controlled by the control device, into an optical path of the sensor system in a calibration mode for the calibration of the sensor system and moves the calibration medium out of the optical path of the sensor system in an operating mode for the testing of measuring objects, in particular bank notes, wherein the calibration medium has more than one reference, wherein the drive, controlled by the control device, moves the calibration medium into the optical path of the sensor system in such a way that one of the references covers a detection area of the sensor system, and the sensor system measures the reference located in the detection area, wherein the drive moves the calibration medium under the control of the control device at least one time by a predetermined stretch or a multiple of the predetermined stretch, so that another one of the references covers the detection area, and the sensor system measures the other reference located in the detection area, and wherein the predetermined stretch corresponds to an extent of the calibration medium's individual references in whose direction the drive moves the calibration medium.
