Definitions

  • a device for determining the emission spectra in securities with fluorescent security features, which has a high-resolution spectrophotometer, a suitable excitation energy source and optionally serving as a dispersion element narrow-band interference filter.
  • the devices 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, to check the authenticity and / or the state and / or the nominal value of the banknotes BN being tested.
  • 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 irradiated by means of an imaging optical system 15, 16, 17 on a banknote to be tested.
  • the imaging optics comprises a collimator lens 15, a deflection mirror as a beam splitter 16, in particular a dichroic beam splitter 16, which emanating from the laser diode 14 and through the collimator lens 15 deflects laser beam formed by 90 °, and a condenser lens 17 with a large opening angle, which images the deflected laser beam through a front glass 18 preferably perpendicular to the conveyed by the transport system 5 in the direction T to be examined banknote BN and thus the banknote BN for emission stimulated by luminescence radiation
  • 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 concave mirror 26, which preferably images the luminescence radiation of first order or minus 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 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.
  • 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 checked.
  • 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 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 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

  • 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.

  • individual pixels 40 have different dimensions, in particular in the direction of dispersion of the luminescence radiation to be measured, as described in US Pat Fig. 7 is shown.

  • the parallel readout of a plurality of pixels 40 or pixel groups thereby made possible short integration times and a synchronized measurement of the banknote BN. This measure also contributes to an increase in the signal-to-noise ratio.
