Definitions

  • the invention relates to a device and a method for testing, in particular, luminescent value documents, wherein the value document is irradiated with light and the luminescence radiation emanating from the value document is detected spectrally resolved.
  • Such luminescent value documents may e.g. Banknotes, checks, coupons or chip cards.
  • the present invention is primarily concerned with the validation of banknotes. These typically contain in the paper or in the ink a feature substance or a mixture of several feature substances which exhibit a luminescent behavior, such as e.g. fluoresce or phosphoresce.
  • a system is for example from the DE 23 66 274 C2 known.
  • This system to check the authenticity of a banknote, ie in particular the test, whether a fluorescent feature substance is actually present in a banknote to be tested, obliquely irradiated and detected the vertically remitted fluorescence spectrally resolved by means of an interference filter.
  • the evaluation is carried out by comparing the signals from different photocells of the spectrometer.
  • an object of the present invention an apparatus and a method for testing luminescent value documents to provide a safe test with a compact luminescence sensor.
  • the devices according to the invention can be used in all types of devices in which optical radiation, in particular luminescence radiation, is tested. Although not limited thereto, the following describes as a preferred variant the checking of banknotes in banknote processing devices, which can serve, for example, for counting and / or sorting and / or depositing and / or paying out banknotes.
  • the banknote sorting device 1 in this case has an input compartment 3 for banknotes BN in a housing 2, into which banknotes to be processed BN can either be input manually from the outside or banknotes bundles can be fed automatically, if necessary after a preceding debrapping.
  • the banknotes BN entered into the input compartment 3 are separated from the stack by a singler 4 and transported through a sensor device 6 by means of a transport device 5.
  • the sensor device 6 can have one or more sensor modules integrated in a common housing or mounted in separate housings. The sensor modules can serve, for example, for checking the authenticity and / or the state and / or the nominal value of the banknotes BN being checked.
  • the checked banknotes BN are then output sorted into output pockets 9 as a function of the test results of the sensor device 6 and of predetermined sorting criteria via switches 7 and associated spiral stackers 8, from which they are optionally manually removed after previous banding or packaging or can be removed automatically. It can also be a shredder 10 may be provided in order to destroy bills classified as genuine and no longer fit for circulation BN.
  • the control of the banknote sorting device 1 takes place by means of a computer-assisted control unit 11.
  • the sensor device 6 can have different sensor modules.
  • the sensor device 6 is distinguished in particular by a sensor module 12 for testing luminescence radiation, which is referred to below as the luminescence sensor 12 for short.
  • FIG. 2 FIG. 4 illustrates, in a schematic cross-sectional view, the internal structure and arrangement of the optical components of a particularly compact luminescence sensor 12 according to an embodiment of the present invention.
  • Fig. 3 also shows a top view of a part of these located inside the luminescence sensor 12 components.
  • This luminescence sensor 12 is designed to be particularly compact and optimized with regard to high signal-to-noise ratios.
  • the luminescence sensor 12 has in particular in a common housing 13 both one or more light sources 14 for exciting luminescence radiation, as well as a detector 30, preferably a spectrometer 30 for the spectrally dispersed detection of the luminescent light.
  • the housing 13 is closed so that unauthorized access to the components contained therein is not possible without damaging the housing 13.
  • the light source 14 may, for. B. an LED, but preferably be a laser light source such as a laser diode 14.
  • the laser diode 14 may emit one or more different wavelengths or wavelength ranges. If you work with several different wavelengths or wavelength ranges, can also be provided that in the same light source housing or in separate light source housings, ie separate light source modules, multiple light sources 14 for different wavelengths or wavelength ranges, for example, are arranged side by side and preferably emit parallel light that can be projected onto the same location or adjacent locations of the banknote BN.
  • the light sources 14 can emit light of a plurality of different wavelengths or wavelength ranges, it can be provided that the individual wavelengths or wavelength ranges can be selectively activated.
  • the light emanating from the laser diode 14 is radiated by means of imaging optics 15, 16, 17 onto a banknote to be tested.
  • the imaging optics include a collimator lens 15, a deflection mirror as a beam splitter 16, in particular a dichroic beam splitter 16, which deflects the emanating from the laser diode 14 and formed by the collimator lens 15 laser beam by 90 °, and a condenser lens 17 with a large opening angle, which the deflected laser beam through a front glass 18 preferably perpendicular to the transported by means of the transport system 5 in the direction T transports to be examined banknote BN and thus the banknote BN to emit emission of luminescent radiation.
  • the luminescence radiation emanating from the illuminated banknote BN is then preferably likewise detected in the vertical direction, ie coaxially with the excitation light. This leads to a lower susceptibility due to positional tolerances of the transported banknotes BN on the measurements as in the oblique illumination, for example DE 23 66 274 C2 ,
  • the optics for imaging the luminescence radiation onto a photosensitive detector unit 21 likewise comprises the front glass 18, the condenser lens 17 and the mirror 16 at least partially transparent to the luminescence radiation to be measured.
  • the optic subsequently has another condenser lens 19 with a large opening, followed by a filter 20, which is designed to block the illumination wavelength of the light source 14 and other wavelengths not to be measured, and a deflection mirror 23.
  • the deflecting mirror 23 serves to fold the beam path and to redirect the luminescence radiation to be measured to an imaging grating 24 or another device for spectral decomposition 24.
  • the deflection mirror is advantageously mounted parallel or nearly parallel to the image plane of the spectrometer for an extremely compact design (angle ⁇ 15 degrees).
  • the imaging grating 24 in this case has a wavelength-dispersing element with a concave mirror 26 which preferably images the luminescence radiation of the first order or minus the first order onto the detector unit 21.
  • the detector unit 21 preferably has a detector row 22 of a plurality of photosensitive pixels arranged in series, ie pixels, as they are z. B. in relation to the FIGS. 6 or 7 will be described below by way of example.
  • the entrance slit of the spectrometer 30 is in the Fig. 2 denoted by the reference symbol AS.
  • the entrance slit AS can be present in the housing 13 in the form of a diaphragm AS in the beam path. However, it is also possible that at this point no aperture is present, but only a "virtual" entrance gap AS is present, which is given by the illumination track of the light source 14 on the banknote BN. The latter variant leads to higher light intensities, but can also lead to an undesirable greater sensitivity to ambient light or stray light.
  • the deflecting mirror 23 is positioned with respect to the imaging grating 24 so that the entrance slit AS falls onto the region of the deflecting mirror 23. Since in this way the beam cross section of the radiation to be deflected on the deflection mirror 23 is particularly small, the deflection mirror 23 itself can also have particularly small dimensions. If the deflecting mirror 23 is a component of the detector unit 21, the deflecting mirror 23 can thereby not only according to FIG FIG. 2 above, but also adjacent to the photosensitive areas of the detector unit 21 are attached.
  • a particular idea of the present invention is that the light source 14 for the excitation of luminescence radiation generates an elongated illumination surface 35 extending in the transport direction T on the banknote BN to be tested.
  • This variant has the advantage that the luminescent, in particular phosphorescent feature substances present in the banknotes BN are usually pumped up longer by the illumination surface extending in the transport direction during the onward transport at the luminescence sensor 12 and, in particular, the radiation intensity of the luminescent phosphorescent feature substances is thereby increased ,
  • FIG. 5 illustrates a related snapshot.
  • An elongated illumination surface 35 extending in the transport direction T can be understood to mean that the illumination radiation at any given time irradiates an arbitrarily shaped surface, in particular a rectangular track on the banknote, which is significantly larger in the transport direction T than perpendicular to the transport direction T.
  • the extent of the illumination surface 35 in the transport direction T at least twice, especially preferably be at least three times, four times or five times as long as the extension perpendicular to the transport direction T.
  • Fig. 5 With another hatching also the image surface 36, ie the entrance hatch 36 of the spectrometer 30 is illustrated, ie that region of the banknote BN which is imaged on the spectrometer 30 at the given time in accordance with the dimensions of the entry slit AS. It can be seen that the length and width of the entrance hatch 36 of the spectrometer 30 are preferably smaller than the corresponding dimensions of the illumination surface 35 of the laser diode 14. This allows greater adjustment tolerances for the individual sensor components.
  • the illumination surface 35 extends substantially further in the transport direction T as compared to the transport direction T compared to the image surface 36. This is particularly advantageous for exploiting the increased inflation effect.
  • the illumination surface 35 and the image surface 36 overlap only partially in the transport direction T.
  • the luminescence sensor 6 can be used both in devices 1 in which the banknotes BN are transported in the illustrated transport direction T and in devices 1 in which the banknotes BN be transported in opposite direction -T.
  • different detector units 21, 27 are used for detecting the luminescence radiation, in particular the luminescence radiation emanating from the device for spectral decomposition 24, ie, for example, the imaging grating 24.
  • a filter may be provided to only one or more given wavelengths or regions to be measured, wherein the measurable spectral regions of the different detector units 21, 27 are preferably different and, for example, only partially or not overlap.
  • a plurality of further detector units 27 may be present, which measure in different wavelengths or ranges.
  • the plurality of further detector units 27 may be spaced apart from each other or may be in a sandwich structure, as shown in FIG DE 1 0127 837 A1 is described by way of example.
  • the detector line 22 is designed for spectrally resolved measurement of the luminescence of the banknote BN, by means of the at least one further detector unit 27 thus at least one other measurement of the luminescence, such as additionally or alternatively also a measurement of the broadband non-spectrally resolved zeroth order of the spectrometer 30 and / or the decay behavior of the luminescence radiation are performed.
  • the further detector unit 27 can also be designed to check another optical property of the at least one feature substance of the banknote BN. This can be done, for example, by the measurements mentioned at other wavelengths or wavelength ranges.
  • the further detector unit 27 can also be designed to check another feature substance of the banknote BN. So z. B. the detector line 22 for measuring the optical properties of a first feature substance of the banknote BN and the further detector unit 27 for measuring another feature substance of the banknote BN, in particular in a different spectral range than the detector line 22, be designed.
  • the detectors 22, 27 will preferably have filters to suppress unwanted scattered light or higher order light in the measurement.
  • this further detector unit 27 in particular when it is designed for measuring zeroth order of the spectrometer 30, tilted with respect to the imaging grating 24 and the detector line 22 may be arranged to avoid a disturbing back reflection on the concave mirror 26 ,
  • a radiation-absorbing light trap such as a black-colored surface at the end of the beam path of the outgoing radiation from the further detector unit 27 may be present.
  • a reference sample 32 with one or more luminescent feature substances which may have an identical or different chemical composition to the luminescent feature substances to be tested in the banknotes BN.
  • this reference sample 32 may be integrated in the housing 13 itself and be applied, for example, as a film 32 on a further light source (LED 31), which is arranged opposite to the laser diode 14 with respect to the beam splitter 16.
  • the reference sample 32 may instead be, for example, a separate component between the LED 31 and the angle mirror 16.
  • the reference sample 32 can then be excited by irradiation by means of the LED 31 to a defined luminescence, which is mapped by parasitic reflection on the dichroic beam splitter 16 on the detector line 22 and evaluated.
  • the luminescent feature substances of the reference sample 32 can preferably emit broadband, for example over the entire spectral range detectable by the spectrometer 30.
  • the luminescent feature substances of the reference sample 32 may alternatively or additionally also have a specific characteristic emit spectral signature with narrowband peaks to perform wavelength calibration.
  • the reference sample 32 can therefore also be mounted outside of the housing 13, in particular on the side opposite to the banknote BN to be measured, and e.g. be integrated in a counter element, such as a plate 28.
  • an additional detector unit 33 may be present as a separate component or integrated in the plate 28.
  • the additional detector unit 33 may be e.g. one or more photocells for measuring the radiation of the laser diode 14 and / or the luminescence radiation of the banknote BN which has passed through the front glass 18 and possibly through the banknote BN.
  • the plate 28 may be slidably mounted in a guide in the direction P, so that either either the reference sample 32 or the photocell 33 can be brought into alignment with the illumination radiation of the laser diode 14.
  • the plate 28 is preferably connected to the housing 13 via a dotted connection element 55, which lies outside the transport plane of the banknotes BN.
  • a dotted connection element 55 which lies outside the transport plane of the banknotes BN.
  • horizontally extending cross-sectional plane is then in an approximately U-shaped form of housing 13, connecting surface 55 and plate 28 before.
  • This attachment of the plate 28, also in an alternative variant without reference sample 32 and photocell 33, has the advantage that a light protection against unwanted leakage of the laser radiation of the laser diode 14 is given. If the plate 28 for maintenance purposes or for removing jams releasably on the housing 13th is fixed, it can be provided that when dissolved or removed plate 28, the laser diode 14 is deactivated.

  • the arrangement of the optical components in the luminescence sensor 6 according to Fig. 4 differs from the luminescence sensor 6 after Fig. 2 in particular the fact that it is possible to dispense with the deflecting mirror 23. It should be noted that the luminescence sensor 6 after Fig. 4 also has no further detector units 31, 33, although this would also be possible.
  • the dichroic beam splitter 16 does not deflect the illumination radiation but the luminescence radiation in a mirrored manner.

  • the use of such a filter with wavelength gradients filter 64 has the advantage that the light to be tested are irradiated directly to the detector 61 and on Welleninnddispergierende elements such as the grating 24 or the deflection mirrors 23, 57 can be omitted.
  • the structure of the luminescence sensor 1 can thereby be designed particularly simple and with fewer components.
  • the active optical adjustment of individual components can be used not only in the particularly preferred example of a luminescence sensor, but also in other, in particular other optical sensors with advantage.
  • the special design of the spectrometer is also advantageous if the luminescence sensor itself has no light source for exciting luminescent radiation.
  • the system according to the invention can also be designed so that the measured values of the luminescence sensor 12 of a banknote BN are still evaluated, while at the same time measured values of a subsequent banknote BN are already recorded.
  • the evaluation of the measured values of the preceding banknote BN must be carried out so quickly that the individual points 7 of the transport path 5 can still be switched sufficiently fast in order to divert the preceding banknote BN into the respectively assigned storage compartment 9.
  • the devices and methods according to the invention enable a simple and reliable testing and differentiation of luminescent value documents.
  • the test can be carried out, for example, by generating a light having a first wavelength with a predetermined intensity by means of the light source 14 for a specific time period 0-tp for the excitation of the feature substance.

  • the intensity of the emitted luminescent light increases during the time period 0-tp of the excitation according to a certain law.
  • the manner of increase and decrease in the intensity of the emitted luminescent light depends on the feature substance used and on the exciting light source 14, ie its intensity and wavelength or wavelength distribution. After completion of the excitation at time t P , the intensity of the emitted luminescent light decreases according to a certain law.
  • the luminescent light emanating from the bank notes BN is detected and evaluated.
  • the signal of the detector unit 21 at one or more specific times t 2 , t 3, it can be checked particularly reliably whether a genuine banknote BN is present, since only the feature substance used for the banknote BN or the combination of feature substances used has such a decay behavior .
