Definitions
- the invention relates to a device for examining documents in particular value, ID or security documents, with at least two detector units for detecting light emitted by one to be examined Document runs out.
- ID, security or Documents of value such as Banknotes with security features or printed with suitable security printing inks.
- Security features or security printing inks can be luminescent Contain substances which e.g. through light, electric fields, radiation or sound can be stimulated to glow.
- the documents are made to glow and that by Luminescent substances of the document emitted luminescent light detected. Based on the intensity and / or spectral characteristics of the Luminescent light can then be used to determine whether the document is genuine or fake is.
- Certain security features or security printing inks stand out also by a characteristic reflection and / or transmission behavior in certain spectral ranges. For example, becomes a document of value imitated with the help of a color copier, so you can mostly reproduce only the visible color impression of a printed area. Since commercially available color particles, however, not for security features characteristic spectral behavior in certain, in particular have invisible spectral ranges falsified documents in general by appropriate measurement their reflection and / or transmission behavior in these spectral ranges detect.
- the reliability of statements about the authenticity of the checked documents is particularly dependent on the accuracy with which is the spectral characteristic, i.e. the color of a document outgoing light is analyzed.
- Such an analysis can, for example done by spectrometers, which however are relatively high require technical effort and high manufacturing costs.
- Individual detector units e.g. Photodiodes or photomultipliers, each with different spectral Sensitivity. Depending on the spectral characteristics of the document outgoing light, the detector units deliver different detector signals, which are then used for the spectral analysis of light can be.
- devices of this type have the disadvantage that the light detected by the individual detector units on the basis of Parallax errors are generally not from the exact same area of the Of the document. This makes a reliable assessment of the color properties the originating from a certain part of the document Light impossible. This is particularly disadvantageous if Areas with small dimensions, e.g. individual lines of a printed image, to be examined for their spectral properties, because here already slight parallax errors to particularly large inaccuracies in the spectral analysis of the originating from the document Can lead light.
- This object is achieved according to claim 1 in that a scattering element is provided on which the document to be examined outgoing light is scattered, the scattering element and the detector units are arranged so that the scattered light from the detector units can be detected.
- the invention is based on the idea that the different Part of the document outgoing light by means of a diffuser is scattered, taking into account the individual areas Mix components of the light. Individual, side by side Detector units can thereby detect light, which in each case Shares from the different sub-areas of the document.
- the scattering element creates a spatial mix and homogenization of the light emanating from the document.
- the detector units that one common area of the document capture outgoing light equally can. Any parallax errors that occur with a laterally offset arrangement of detector units would occur by the invention intended scatter element greatly weakened. From the of the spectral components of the individual detector units recorded by the document outgoing light can then make statements about the spectral characteristics the luminescence, reflection and / or transmission behavior of the document can be derived with high reliability.
- the diffusing element is for diffuse transmission and / or diffuse reflection of that from the document outgoing light trained. Under a diffuse transmission or reflection is any essentially undirected transmission or to understand reflection.

- the respective Light sources 12 emitted excitation light 15 at different Wavelengths or wavelength ranges.
- This enables more precise Statements about the properties of the banknote 10 Light 16.
- the light sources 12 illuminate the banknote 10 either individually or in combination and that detected in each case with individually or combined illuminated banknote 10 Light 16 is evaluated. First in the example shown in FIG illuminated with only one light source 12, then the detector units detect 1 to 3 three first intensity values. With subsequent lighting With the other light source 12, three second intensity values are generated. With simultaneous illumination with both light sources 12 finally got three third intensity values. By comparison and / or arithmetical linkage of the i.a. different, intensity values will be a particularly thorough study of the properties of the light 16 emanating from the examined banknote 10.

- the light sources 12 for emitting light 15 with spectral components formed in these spectral ranges should be, the light sources 12 for emitting light 15 with spectral components formed in these spectral ranges.
- luminescent light 16 in is excited or on the bank note 10 by the light 15 of the light sources 12.
- a corresponding one Luminescence is therefore referred to as photoluminescence.
- electrical fields, Radiation or sound other types of luminescence phenomena such as e.g. Electro-, radio- or sonoluminescence stimulated in or on the banknote 10 become.

Accordingly, the differ from the Detector units 1 to 3 generated detector signals S, which for evaluation and analysis of an evaluation device 9 are supplied.
- a first device 13 is provided, which the the bank note 10 directs outgoing light 16 onto the detector units 1 to 3, especially focused.
- This can be an imaging optic act, which a portion 11 of the banknote 10 on the detector devices Depicts 1 to 3.
- Selfoc lenses are used.

- an as is in front of the individual detector units 1 to 3 Diffuser 5 formed scattering element is provided, on which the the banknote 10 outgoing light 16 is scattered.
- the scatter results in the example shown, of a diffuse transmission of light 16 through the lens 5. This process is in the figure by a variety small arrows 8 indicated.
- the device has an aperture 4, in particular an aperture Perforated or slit diaphragm. Together with the selfoc lens first device 13 becomes a particularly simple and precise aperture limitation reached.
- the aperture for example by combining the Aperture 4 with a light guide element, e.g. based on glass and / or Plastic fibers, or by combining a light guide with a imaging optics, which the portion 11 of the bank note to be examined 10 on the light guide, in particular in a glass and / or Plastic fiber inside, maps.
- Fig. 2 shows a second embodiment of the invention, in which in the difference to the embodiment shown in Fig. 1 instead of one Diffuser 5 a reflector 6 is used as a diffuser. That from the Banknote 10 outgoing light 16 is on the reflector 6, for example one matt or roughened mirror, diffusely reflected and then from the individual detector units 1 to 3 arranged next to one another.
- the functionality of all other components of the device is analogous to the example described in Fig. 1.
- Light 16 can also be used as an integrating sphere. This is what it is about is a hollow sphere, the interior of which is diffusely reflective Paint, for example made of magnesium oxide, barium sulfate or Teflon is.
- the light 16 emanating from the banknote 10 occurs in a first Opening in the Ulbricht sphere, becomes several times diffuse inside reflects and exits through another opening. The passage of incoming light directly to the outlet opening is by appropriate additional means inside the sphere, e.g. Reflectors, prevented.
- the diffuse light emerging from the Ulbricht sphere can then emanate from the Detector units 1 to 3 can be detected.
- Another possibility for spatial mixing of the banknote 10 outgoing light 16 represents a scattering element designed as a hologram in which light rays emanating from the banknote 10 in a large number of light beams split in different directions and in this way before hitting the detector units be mixed.
- An optical filter (not shown) can be placed in front of the scattering element 5 or 6. be arranged which e.g. only for those spectral components of the from the banknote 10 outgoing light 16 is transparent, which of the behind the scattering element 5 or 5 arranged detector units 1 to 3 detected should be.
