Definitions
- the present invention relates to a device for checking the Authenticity of documents, especially banknotes.
- a feature substance applied to the document by means of a Proof sensors to check the authenticity of the respective document As a rule, the document is determined with a light Illuminated wavelength. By the light of the specific wavelength the feature substance itself excites light of a different wavelength, so-called Luminescent light to emit. The remittance from the document Light is detected by a detector and the document becomes real recognized if the detector detects the luminescent light.
- the feature substances, the z. B. in printing inks, special security elements such as security threads, Holograms etc. are often included on only one Side, d. H. applied to one of the surfaces of the documents.
- the sensors used for the detection as reflectance sensors are formed in which the light source and detector coexist must be on the same page of the document to be examined in order to to be able to guarantee proof of the authenticity of a document, two such sensors are provided on either side of the examining documents.
- the known devices for checking the authenticity of documents thus have the disadvantage that by using two sensors cause great effort.
- it is in the known Devices not possible, a particularly compact structure to achieve, because on the one hand two sensors, one for each side of the examined Documents that need to be provided and because these sensors on the other hand have a large design, since light source for lighting of the documents to be examined and detector arranged side by side Need to become.
- the invention is based on a device for checking the Authenticity of documents, in particular banknotes, with a light source, which generates light of a first wavelength and a detector for the detection of light of a second wavelength which is transmitted from one applied to at least one surface of documents to be checked Characteristic substance generated when illuminated with the light of the light source from, the light source being arranged opposite the detector is, documents to be checked between light source and Detector can be introduced.
- the invention thus has the particular advantage that a compact Construction is possible because the light source and detector are not next to each other must be arranged.
- the effort is halved, since only one Light source and a detector are required, because when checking the Authenticity of the feature substances also by means of a transmission measurement can be recorded reliably if the feature substances only on one side of a document to be checked are applied.
- an interference filter is provided in front of the light source and / or the detector.
- the Interference filter in front of the light source only lets light of the first wavelength happen, whereas the interference filter in front of the detector only light the second wavelength.
- the preferred embodiment has the advantage that light from others Wavelengths are reflected by the interference filters.
- This will by the interference filter in front of the detector is the one from the light source
- Light of the first wavelength reflects and the document to be checked is additionally illuminated on its underside.
- the interference filter before Light source reflects the light of the second wavelength, which through the Banknote to be checked occurs and is therefore additionally available at the detector stands.
- Figure 1 shows a schematic representation of a basic structure of a Device 10 for checking the authenticity of documents, in particular of banknotes.
- the device 10 has a light source 20, preferably a light-emitting diode, the light of a certain first wavelength, or a first, narrow limited wavelength spectrum. Facing the light source 20 a detector 45 is arranged, for example a photodiode or a phototransistor, so that the device 10 a transmission measurement one too checks banknote 13.
- the light from the light source 20 excites you Characteristic substance on banknote 13, which is on one or both surfaces the banknote 13 is applied to a second luminescent light Wavelength, or a second, narrowly limited wavelength spectrum, to generate, which is from the first wavelength of the light source 20th different.
- the luminescent light is detected by the detector 45 and on Output signal of the detector 45 is based on the presence of a corresponding Signals monitors the existence of the authenticity of the checked banknote approved.
- Figure 2 shows a schematic representation of the authenticity check a banknote.
- the light source 20 generates a light P with the specific, first wavelength and a predetermined intensity I for a specific time 0-t P for the excitation of the feature substance.
- the feature substance of the bank note 13 to be checked is excited by the light from the light source 20, whereupon the feature substance emits luminescent light PL of the second wavelength.
- the intensity of the emitted luminescent light PL increases during the time 0-t P of the excitation according to a certain law, e.g. B. exponentially.
- the way of increasing and decreasing the intensity of the emitted luminescent light PL depends on the feature substance used and on the stimulating light source, ie its intensity and wavelength.
- the intensity of the emitted luminescent light PL decreases according to a certain law, e.g. B. reversely exponential.
- a certain law e.g. B. reversely exponential.
- the decay behavior can be checked by comparing the intensity of the luminescent light PL described above at one or more specific points in time with predetermined intensities for real banknotes 13. It can also be provided that the course of the intensity of the luminescent light PL is compared with predetermined courses for known banknotes 13.
- a filter 30 that between Light source 20 and banknote 13 to be checked is provided that only lets light of the first wavelength pass.
- a filter 35 can also be provided between bank note 13 and detector 45 that only light of the second wavelength, d. H. Pass luminescent light leaves. This can prevent light of the first wavelength comes to a significant extent to the detector 45, whereby faulty Checks of the authenticity of the banknote 13 can be avoided.
- Interference filters are preferably used for the filters 30 and / or 35, which are in particular complementary to each other, because in addition to the fact that they only let light of a given wavelength pass through, have the additional effect of reflecting light of other wavelengths the filter 30 between light source 20 and Banknote 13 designed as an interference filter, can only light the one hand first wavelength from the light source 20 to the banknote 13.
- the one emitted by the feature substance of the banknote 13 Luminescent light of the second wavelength reflected by the filter 30 penetrates through the banknote 13 and can be detected by the detector 45. Thereby it is achieved that the detector 45 has more luminescent light available stands, whereby the measurement is improved.
- the filter 35 between banknote 13 and detector 45 becomes an interference filter formed, on the one hand only luminescent light of the second wavelength from the banknote 13 to the detector 45.
- the light of the first wavelength of the filter 35 reflects and now hits the underside of the banknote 13, which allows more light of the first wavelength to excite the feature substance the banknote 13 is available. This will in turn generates more luminescent light of the second wavelength and can additionally can be detected by the detector 45.
- the detector 45 thus has more luminescent light available, which improves the measurement. All in all it is thus achieved that both a measurement in transmission (light first wavelength of light source 20) as well as a measurement in remission (Light of the first wavelength reflected by the filter 35) is made.
- banknote is of course maximized in the event that both the filter 30 between the light source 20 and bank note 13 and the filter 35 are formed as an interference filter between banknote 13 and detector 45.
- windows 11 and 12 are shown in FIG. 1, which are optional may be present, e.g. B. as covers of housings for the light source 20 or the detector 45 to prevent contamination or wear To prevent light source or detector 45.
- the windows 11 and 12 have no significant influence on the behavior of the Device 10.
- the device 10 with the light source 20 and the opposite detector 45 as a transmission sensor becomes a special one simple optical structure allows, in particular none imaging optics for light source 20 and / or detector 45 is required.
- a further filter 40 between filter 35 and detector 45 to provide which only light of the second wavelength pass lets and is preferably designed as an absorption filter.
- the absorption filter 40 can be a component a bracket, cover or the detector 45 itself ..
- interference filters as a composite of several layers together with absorbent filters, so the absorbent layers advantageously oriented so that they face away from the sample. With a composite solution it is particularly advantageous that the different angular dependence the filter edges of the absorption filter and interference filter compensates differently with the angle of incidence by their combination.
- the bank note 13 can be used to check the authenticity in a direction T be transported lengthwise or crosswise through the device 10, but it is also possible to carry out the check when the banknote 13 is stationary.
- a full-area measurement can also be carried out or check the banknote.
- several devices 10 arranged side by side in a row d. H. on the one hand several light sources 20 are arranged in a line next to one another, whereas on the other hand several detectors 45 side by side to be ordered.
- a very compact structure is possible because the Light sources 20 or detectors 45 are arranged very close to one another can be because z. B. no imaging optics is required. Thereby high resolution can be achieved.
- Detector 45 In order to improve the checking of the authenticity of the banknotes or to improve the detection of counterfeits, provision can be made for the excitation shown in FIG. 2 with the light P of the first wavelength during the period 0 to t P at a time t 1 by means of Detector 45 is checked whether luminescent light can be determined which has a particularly high intensity I, which exceeds the expected intensity of the luminescent light PL. Luminescent light with a particularly high intensity during the excitation indicates a counterfeit feature substance.
- Checking the authenticity of the banknotes or detecting counterfeits can be further improved if at least one more Light source is provided that generates light of a wavelength that of deviates slightly from the first wavelength, d. H. a slightly larger one or has a smaller wavelength. Is the banknote to be checked with Illuminated to the light of the further light source (s), no luminescent light may be stimulated. It is obvious that the suggestion with the different Wavelengths or wavelength ranges take place in succession got to. In the event that luminescent light from the banknote or the feature substance is generated even if the excitation light is not the first Has a wavelength, there is a counterfeit banknote or a counterfeit one Feature substance before.
- At least one additional detector checked one or more wavelengths that were slightly larger or are smaller than the second wavelength of the luminescent light. Since that from a real banknote or a real feature substance emitted luminescent light has a narrowly limited spectrum, indicates light with a wavelength, those above and / or below this narrowly limited spectrum the first wavelength indicates that there is a forgery.
- a further improvement of the authenticity check or the recognition counterfeiting can be achieved if the feature substance, the especially for banknotes e.g. B. in a printing ink and / or a security element, such as a security thread or a hologram can be a certain spatial distribution on the surface or the surfaces of the banknotes.
- the spatial distribution can then z. B. detected by means of the device if it has the line structure described above, the full coverage of the banknotes to be checked at Allows transport of the banknotes through the device.
- luminescence can understand both fluorescence and phosphorescence become.
