Definitions

  • the invention relates to a device and a method for detecting light emitted by a security document, and a method for producing such a device.
  • Optical systems which are used to detect the emitted light regularly consist of a number of lenses which image the surface or a partial area of the surface of the security document in a detector plane of an optical sensor.
  • the light intensity i.e. the amount of light per detector surface
  • the square of the measuring distance which, for example, denotes a distance between an entrance surface of the optical system and the surface to be imaged
  • optical systems with a large aperture and a small measuring distance are used for weakly luminous surfaces in order to capture as much light as possible.
  • the aperture designates a diameter of an entry opening of the optical system, in particular the diameter of an entry lens.
  • the entry surface can be the same as the detector surface, in particular if light from the surface hits the detector directly, ie without radiating through further optical elements.
  • small measurement distances in particular measurement distances that are smaller than a focal length of an entry lens of the optical system, lead to light losses in the system due to beam divergence, with the light being able to be absorbed by the housing, for example.
  • Such systems also lead to an increased dependency of the measurement result both on the measurement distance and on a position of the security document relative to an optical axis of the optical system.
  • using such an optical system may require high positioning accuracy.
  • each lens of the optical system causes small reflections and thus light losses.
  • a further disadvantage consists in the high construction costs and the large installation space requirement of these optical systems with lenses.
  • the DE 27 13 396 A1 discloses a method and apparatus for marking or identifying a body containing or carrying luminescent material.
  • the EP 2 573 739 A1 discloses a method for authenticating security documents, which method is directed to a simple device and method for authenticating an optically variable unit.
  • the GB 2 507 575 A discloses an authentication device for authentication of a security feature.
  • the EP 2 043 058 A2 discloses a bill identification device provided in automatic vending machines and money changing machines.
  • the technical problem arises of creating a device and a method for detecting emitted light from a security document and a method for producing such a device, which enable a desired amount of light to be detected, but at the same time require space, weight, construction costs and light losses and positioning sensitivity reduce.
  • a basic idea of the invention is to design a device for detecting light emitted by a security document without a lens.
  • a light channel can be provided with a free-body shape, the free-body shape being chosen such that a surface of the security document to be imaged with a predetermined geometry through the light channel of the device onto an optical Sensor, in particular on its active surface, is imaged with a predetermined geometry.
  • the light emitted, reflected or scattered by the surface to be imaged can be directed completely or to a large extent through the light channel onto the active surface.
  • a device for detecting emitted light from a security document is proposed.
  • the light is emitted from the security document, in particular from the surface of the security document.
  • the emitted light can denote diffusely scattered light, reflected light, transmitted light or emitted light.
  • security document protected by security features or elements.
  • Security features are features that at least make falsification and/or duplication more difficult than simple copying.
  • Physical entities that include or form a security feature can be referred to as security elements.
  • a security document can include multiple security features and/or security elements. As defined here, a security document can always represent a security element. Examples of security documents, which also include documents of value that represent value, include, for example, passports, ID cards, driver's licenses, ID cards, access control ID cards, health insurance cards, banknotes, postage stamps, bank cards, credit cards, smart cards, tickets and labels.
  • the security document can in particular contain or have light-scattering, photoluminescent/phosphorescent elements or electroluminescent elements, in particular pigments. These enable an authenticity verification depending on emitted photo- or electroluminescent radiation when such a luminescent element is excited, e.g. by light and/or an electric field. In such a case, however, an optical imaging of a partial area of the surface is not absolutely necessary for the authenticity verification, but only the detection of the amount of emitted light.
  • the device can in particular be part of a device for checking the authenticity of the security document.
  • a device for checking the authenticity of the security document enables the authenticity of the security document to be verified, in particular by evaluating properties of the emitted light.
  • the device comprises at least one light guide body.
  • the light-guiding body can be designed as a coated glass body or can include such a body.
  • the light-guiding body can be designed as a solid profile with at least one light-guiding channel filled, for example, with air or another transparent material.
  • the light-guiding body has at least one light channel or forms one.
  • the light channel has an entry opening and at least one first exit opening.
  • the entry opening and the first exit opening are thus connected by the light channel.
  • the entry opening designates an opening through which the light emitted by the security document enters the light channel.
  • the exit opening correspondingly designates an opening through which the light that has entered and is radiated through the light channel exits or can exit from the light channel.
  • the wall surface or wall surfaces enclosing the light channel are designed to be completely reflective. This means that no light can escape from the light channel through the wall surface/s.
  • the wall surface/s can be designed to be reflective.
  • the light guide body is designed without lenses. This means that the light-guiding body does not include a lens or an element that has an optically equivalent effect. In particular, the light guide body does not include a lens or an optically equivalent element that is used for optical imaging and/or light bundling.
  • the feature that the light-conducting body is designed without lenses can mean that the light channel is designed in such a way that a direction of the light entering the light channel through the entry opening is changed exclusively by reflection on the wall surfaces.
  • the feature that the light guide body is designed without lenses can mean that a beam refraction, beam focusing and/or beam scattering of the light entering the light channel through the entry opening takes place exclusively through reflection on the wall surfaces. It is therefore not possible to arrange an optical element for changing the beam direction of the light, for beam refraction, for beam bundling and/or for beam scattering in and/or along the light channel.
  • the fact that the light-guiding body is designed without lenses does not necessarily mean that one or more optical elements, e.g. mirrors or beam splitters, are included in the light-guiding body.
  • optical elements e.g. mirrors or beam splitters.
  • such optical elements are not used for light bundling and/or optical imaging.
  • the inlet opening and/or the first outlet opening can be designed without a lens. This means that at the inlet and/or outlet opening there is no change in the beam direction of the light, no beam refraction, no beam bundling and/or no beam scattering, in particular by an optical element, takes place.
  • the light channel can thus be in direct optical connection with an environment via the entry opening. This can mean that light from the environment can radiate into the light channel without changing properties. Furthermore, the light channel can be in direct optical connection with an environment via the exit opening or with an optical sensor, which will be explained in more detail below. This can mean that light can radiate from the light channel into the environment or onto the optical sensor without changing properties.
  • the light-guiding body can be formed without an imaging element, with the light-guiding body not comprising any element for optical imaging. However, this does not preclude the light guide body from guiding the beam to detect light.
  • a shape and an area of the entrance opening is different from the shape and an area of the exit opening.
  • an inlet opening can be rectangular and an outlet opening can be circular or vice versa.
  • rays from an emitting strip of the security document can be directed onto a circular active surface without major light losses, in particular due to multiple reflection.
  • optical imaging is not required if only the amount or intensity of the light emitted from areas of the surface of the security document is to be detected.
  • the proposed device advantageously enables the emitted light to be recorded with as little loss as possible, with construction costs and the need for construction space being minimized because of the lenses that are not required.
  • the light channel is designed as a free-form body.
  • a design of the free-form body in particular the design of the entry and exit openings, can be selected as a function of a geometry and position of a radiating surface (surface to be imaged) and as a function of a geometry of an active surface of an optical sensor.
  • the entrance opening to any geometry and / or position of the radiating Surface and the outlet opening are adapted to the geometry of the active area of a sensor.
  • the light channel in particular the geometric shape of the free-form body and the geometry of the entry and exit openings, can be selected in such a way that a surface of the security document to be imaged with a predetermined geometry passes through the light channel of the device onto an optical sensor, in particular on its active surface. is mapped with a predetermined geometry.
  • the area to be imaged can be rectangular, square, circular, or oval.
  • the active area can be rectangular or square. Other geometric shapes are also conceivable here.

  • a predetermined percentage e.g. more than 90 % or more than 95% of which are directed through the light channel onto the active surface.
  • the shape of the light channel can thus be selected depending on the geometry of the area to be imaged and the active area of the desired optical sensor. In this way, a reliable optical detection of a surface to be imaged with a predetermined geometry and with a desired optical sensor can advantageously take place. If an optical sensor with a predetermined geometry is to be used, the shape of the light channel can advantageously result in good optical detection for different surfaces to be imaged. A flexible adaptation of the optical detection can thus take place.

  • the device comprises at least one optical sensor, the optical sensor being arranged in or on the first outlet opening.

  • a geometry of the outlet opening and/or dimensions of the outlet opening can correspond to the geometry or dimensions of the active surface.
  • the active surface at the exit opening can also be arranged inside the light channel. This can mean, for example, that the light channel encloses the active surface of the optical sensor at its exit opening. In this case, there can be no distance or a predetermined (small) distance between the wall surface of the light channel and the active surface. If there is no distance, the wall surface of the light channel can be arranged flush with the edges of the active surface at the first exit opening.
  • the light channel can thus be in direct optical connection with the active surface of the optical sensor via the exit opening. In this case it can be possible that no light emerges from the first exit opening into an environment.
  • the optical sensor in particular its active surface, can also be arranged outside of the first exit opening.

  • a central axis z 1 of the first partial channel 11a is shown, which corresponds to the central axis z of the main channel section 16 of the light channel 6 , the central axis of the main channel section 16 corresponding to a center line of the entry opening 7 . Also shown is an inlet opening 18 of the first partial channel 11a, with the central axis z 1 corresponding to a center line of the inlet opening 18 of the first partial channel 11a. Wall surfaces of the first sub-channel 11a are inclined relative to the central axis z 1 of the first sub-channel 11a.
  • a central axis z 2 of the second partial channel 11b is also shown.
  • the further central axis z 2 is oriented orthogonally to an inlet opening 17 of the second partial channel 11b and intersects the surface of the further inlet opening 17 at its geometric center.
  • Wall surfaces of the second sub-channel 11b are inclined relative to the central axis z 2 of the further sub-channel 11b.
  • the central axis z 2 of the second partial channel 11b is inclined relative to the central axis z 1 of the first partial channel section 11a.
  • FIG 5 a perspective view of a device 1 of a further example not according to the invention is shown. It is shown here that the light channel 6 is in the form of a truncated pyramid. It is also shown that both the first optical sensor 5 and the further optical sensor 13 are arranged next to one another in the exit opening 8 of the light channel 6 .
  • One dimension of the outlet opening 8 is here adapted to a dimension and geometry of the overall arrangement made up of the first optical sensor 5 and the further optical sensor 13 . In particular, the outlet opening 8 encloses the rectangular envelope of the active surfaces 10, 14 (see FIG 4 ) of the two sensors 5, 13.
  • the optical sensors 5, 13 can be designed to detect mutually different properties of the light 2 or be combined with mutually different optical elements, in particular filter elements.
  • a geometry of the light channel 6 and thus a design and/or arrangement of the wall surface(s) 9, 9a, 9b can be freely selected.
  • the shape and arrangement is adapted to a geometry and/or dimension of the active surface 10, 14 of an optical sensor 5, 13.
  • the design and/or arrangement can also be selected in such a way that there is no back reflection in the light channel 6 .
  • a schematic cross section through a device 1 is shown in a further embodiment. It is shown here that the light channel 6 branches at a junction into a first sub-channel 11a and a second sub-channel 11b.
  • the branching is achieved here by the formation of the light channel 6, in particular by a corresponding wall surface course.
  • the branching is designed in such a way that light 2 from a main channel section 16 of the light channel 6 radiates into the first sub-channel 11a and the second sub-channel 11b in a predetermined ratio.
  • An inlet opening 17 of the second partial channel 11b and an inlet opening 18 of the first partial channel 11a are shown.
  • Central axes z 1 , z 2 of the first sub-channel 11a and of the second sub-channel 11b are also shown. It is shown here that the central axes z 1 , z 2 of the partial channels 11a, 11b are each inclined relative to the central axis z of the main section 16 .
  • a wall surface inclination of a wall surface of the first partial channel 11a and a wall surface of the second partial channel 11b changes along the first or second partial channel 11a, 11b.
  • the wall surfaces of the first and of the second partial channel 11a, 11b are each curved.
  • the proposed device 1 offers several advantages. On the one hand, light losses are reduced since no lenses are used in the device 1. If the exit opening 8, 12 is adapted to the respective optical sensor 5, 13, light losses can also be minimized as a result, in particular if the active surface 10, 14 of the respective sensor 5, 13 completely fills or covers the corresponding outlet opening 8, 12.
  • the proposed device 1 is less sensitive to a lateral position deviation of the radiation source to be measured (e.g. the emitting, reflecting and/or scattering surface of the security document 3) compared to the lens-based embodiment, the lateral position deviation being a deviation perpendicular to the center line of the entry opening 7 designated.
  • the proposed device 1 is also less sensitive to an inclination of the surface of the security document 3 relative to this center line. This means that the amount of light directed towards the at least one exit opening 8, 12 is not dependent on the lateral position deviation and/or inclination, or only to a small extent.
  • the entry opening 7, in particular its geometry and/or dimension can be adapted to a geometry and/or dimension of a security feature of the security document 3. Further, the cost and weight of the device 1 can be reduced. Due to the high light efficiency, more economical optical sensors 5, 13 can also be used, which can also be flexibly selected in terms of their shape. It is also easy to adjust and maintain.
