Definitions
- the invention relates to a hand sensor for the authenticity detection of signets on documents according to the preamble of claim 1 and one with Signet interacting with the sensor, which has at least one Has a distinguishing feature.
- a hand sensor for the authenticity detection of signets on documents according to the preamble of claim 1 and one with Signet interacting with the sensor, which has at least one Has a distinguishing feature.
- Such a sensor is with the object DE 41 17 011 A1, in which in particular diffuse, low-intensity radiation should be recorded, as is the case with the Examination of banknotes provided with luminescence features occur.
- the sensor system described there consists of a conical expanded fiber optic rod and a processing optics, with the narrow cross-sectional end of the fiber rod that of the measurement object incoming radiation can be detected in a large solid angle.
- the Radiation occurs under one due to the cross-sectional change smaller angle, based on the opening angle of the subsequent optics is matched from the fiber rod.
- the excitation is carried out with the help of conventional light sources visible light (for example, incandescent lamps) resulting in a relatively weak one Luminescence signal leads, which is detected by the fiber rod and the Evaluation optics must be supplied.
- visible light for example, incandescent lamps
- the invention is therefore based on the object of a hand sensor for the Training authenticity detection of signets on documents so that luminescent signets (i.e. signs with fluorescence, phosphorescence, Up-conversion, etc. based authenticity features) on the document a much larger area can be recognized on the document and manual operation is possible.
- luminescent signets i.e. signs with fluorescence, phosphorescence, Up-conversion, etc. based authenticity features
- a hand sensor according to the invention is preferably used when authenticity signs that are not recognized by machine are subsequently checked for authenticity should be checked.
- An essential feature of the invention is that of a beam source emitted beam bundle converted by a focusing optics there will be a. on the surface of the document to be examined results in an approximately line-shaped scan line which is arranged on the document Identification feature optically stimulates and the optical response signal via a Detection optics is evaluated by an evaluation unit.
- Identity generally means the authenticity of a document identifying feature used, which is directly on the document itself can be applied, but also in the area of a signet is arranged.
- the term "signet” describes a detachable (for example, applied by gluing) or a trademark or label permanently attached to the document Seal, a delimited area of any kind or a printing area a document on which the identifier is arranged. In the later description is left open whether the identifying feature located directly on the document itself or part of one on the Attached document is which is separable or inseparable from the Document is connected.
- the excitation wavelength is larger than that of Identifying feature emitted reflected wavelength. in the Frequency range expressed this means that the excitation frequency is lower than the response frequency.
- the invention also relates to other excitation mechanisms, such as Example the exploitation of the "normal" fluorescence effect, in which with a certain wavelength is excited and the fluorescent Identifier with a longer wavelength answers what the represents the opposite effect to the mentioned up-conversion effect.
- a third embodiment relates to the fluorescence effect, in which the Excitation is on the same wavelength as the radiation wavelength, but the response pulse is delayed in a defined time interval follows the excitation pulse.
- the signal from the hand sensor should be evaluated be as sensitive as possible in order to recognize relatively weak signets can.
- the laser arranged in the hand sensor generates the strongest, most energetic laser beam possible.
- the Lasers have the lowest possible laser class in order to avoid that high-energy laser in operation for injuries to the human body can lead.
- the invention succeeds with a relatively high energy Laser a highly sensitive scanning of a weakly radiating signet realize because a relatively high energy laser source with a Laser class stronger than class 3A can be used and after the Invention ensures that the laser is only switched on when the hand sensor comes close enough to the scanning surface to be examined was carried out and / or that by measures of beam shaping the Sensor despite the strong radiation source in laser class 3A or lower can be classified.
- the invention proposes a sensor system that detects the approach of the laser to the document surface and evaluates and accordingly the inputs and, if necessary, also Switching off the laser controls.
- a preferred laser class which also has an effective detection low-emission signets and, on the other hand, health hazards excludes, is laser class 3A.
- the in the The hand-held laser only goes into operation when it turns on reliably the head surface is approached or even placed on an object the signet on it was recognized. On this way, eye protection is achieved even with stronger lasers.
- the Approach takes place by scanning the surface of the object. Such scanning can be done using optics and preferably in the IR range working transmitting / receiving arrangement take place, whereby for Example an LED as a transmitter diode and a single or a double photo diode is switched as a receiving diode.
- the scanning beam of this arrangement is the one to be examined Reflected object, then the reflected beam from the receiving photodiode in evaluated the hand sensor and thus the approach to it is reliable Object detected. Only when this approximation has been established will the Laser in operation and scans the object with the laser beam in order to Verify identifier.
- a focused one Optics used that only allows light from the light spot 24 to the Photodiode falls when the object is in front of or very close to that Exit window 7 is.
- a triangulation evaluation can be achieved. If the object is further from Exit window 7 removed, so the light imaged by the light spot 24 strikes which is called a photodiode (first part of the double photodiode) Background diode. If, on the other hand, the object is directly in front of the exit window, then the light falls on the other photodiode (second part of the double photodiode), called foreground diode. This way, the approach can be even more secure can be recognized as having only one photodiode.
- a touching scan may e.g. B. a contact switch, or a Be a pressure sensor that only emits a signal when the head surface of the Hand sensor was placed on the object.
- All of the proximity detections mentioned can preferably be with a hand-operated button (switch or button) can be combined so that only if this button is also pressed and the approach is recognized of the hand sensor to the object of the laser is switched on.
- the sensor can a deeper and therefore less dangerous laser class are classified as without these measures.
- the sensor can because of this Measures can be classified into laser class 3A instead of 3B, which is quite a important difference means.
- this special line optics a more favorable for the evaluation of weak signals, somewhat stronger laser can be used, but it is still a safe one Handling of the hand sensor guaranteed.
- the line optics consist of a cylindrical lens.
- Such simple cylindrical lenses can also be used for lens collectives used, such as. B. a converging lens i. V. m. a cylindrical lens or specially shaped cylindrical lenses.
- the converging lens focuses on the surface of the object, while the cylindrical lens the strongly diverging (defocused) Rays on the object cause the elongated scanning bar generate on the object.
- the hand sensor has an approximately circular cylindrical cross section Housing, which can also be polygonal oval or angular. This housing is designated 19 in FIG.
- One or more batteries or accumulators 20 can be located in the housing be arranged, which serve to power the laser diode 1.
- an external power connection can also be made to the housing be provided.
- a separate battery pack can also be provided which is connected to the hand sensor via a longer cable.
- the laser diode 1 generates a beam 34 which initially has one or more Focusing lens 2 happens. These focusing lenses 2 focus the beam in the X direction (Beam bundle 32 in FIG. 5) essentially on the object plane of the Object 5, which carries the identifier 21.
- line optics 3 follow the focusing lens 2 happens, which in the simplest case consists of a cylindrical lens.
- line optics 3 generally means any optics that are capable of to generate an approximately linear or elliptical scanning bar 22. This Scanning bar 22 is shown, for example, in FIG. 5 and is shown in FIG Connection with this figure described in more detail there.
- the generated beam 31, 32, shown in Figure 5, and summarized as transmission beams 28 in Figure 1, is directed to a deflecting mirror 4, which in Figure 5 has been omitted for simplicity.
- FIG. 3 shows that the head surface 26 (width of the scanning head) is significantly larger than the width of the exit window 7.
- the gem. Fig. 2 generated scanning bar 22 is in the direction of arrow 23 in the direction led to the identification feature 21 via the object 5.
- the term light spot 24 is not intended to imply that it is visible light. It can also be in the invisible area, namely in the IR or are in the UV range.
- a second receiving lens 9 ' be arranged, which brings about a further focusing.
- a receiving element 11 which can be, for example, a photodiode or an avalance photodiode.
- a Photomultiplier can be used instead of the receiving element 11 described here.
- the advantage is achieved that, thanks to the Using a special line optics a transmission beam with steep Beam angle arises, which in turn classifies the hand sensor into one comparatively deep, harmless laser class allowed.
- the following is a first embodiment of proximity detection of the hand sensor to the surface of the object 5 described.
- FIGS. 1 and 4 it can be seen from FIGS. 1 and 4 that by means of a LED 14 a transmission beam - preferably in the IR range - is emitted, which has a deflection mirror 13 and one or more lenses 12 on the Exit window 7 is focused.
- the light-emitting diode beam thus strikes the surface of an object 5 which is touched directly by the window 7 of the hand sensor or in a short time Distance is arranged in front of this window.
- the rays reflected by the object 5 are again on the same Received paths through lenses 12, deflected there via the deflecting mirror 13 and a receiving diode 14 'supplied with a corresponding Electronics is connected.
- the receiving diode 14 As soon as the receiving diode 14 'has a reflected transmission beam Detects proximity sensors, it is ensured that the hand sensor in close or even touching distance sits on the object 5 and only if this is the case, the laser diode 1 is switched on.
- the (touching or non-contact) Proximity detection ensure that the laser is only switched on becomes, if it is ensured that the exit window 7 touching or almost is touching on the object 5.
- a push button 15 can also be arranged in the housing 19 is operated by manual finger pressure and when pressed, the Laser diode 1 is turned on.
- a heat sink 16 for the laser diode can also be in the housing 1 can be installed, which preferably consists of a cooling surface.
- a temperature stabilizing element 17 can also be installed, which z. B. from a heating coil or a Peltier element with a there is an additional temperature sensor.
- the temperature stabilizing element 17 should have a uniform temperature ensure the laser diode 1.
- the Peltier element is the laser diode 1 cools, the heat generated by the Peltier element must pass through another Heat sink 18 are removed.
- heat sinks 16 and 18 described here are not necessary for the solution and can also be omitted if necessary.
- temperature stabilization element 17 can also be in various use cases are eliminated.
- the eye can no longer view this beam as a point on the retina depict.
- This receiving optics is open, i. H. it has an aperture of about 1 and is therefore particularly sensitive to light.
- the laser (laser diode 1) can also be replaced by a strong LED or by another radiation source or surface emitter or by a superluminescent diode.
- line optics can also be dispensed with if the Beam exit already the desired elongated area of the scanning bar 22 has (length 30 and width 29) and is not coherent.
- the Scanning bar 22 can also be a round bar of a certain total Expansion be formed.
- the advantage of the described proximity sensors is, moreover, that if that Object 5 is a clear glass that does not turn on the laser. This is because because the proximity sensors prefer a diffuse rather than one specular reflection on the surface of the object 5 reacts.
- a beam splitter is arranged in front of the receiving element 11, which branches off a certain proportion of the laser light reflected by the object and leads to a detection optics that a reflection of the object generated by the evaluates weak, short laser pulses.
- the radiation component reflected by the object not the receiving element 11 or from one in front of the optical filter 10 arranged receiving element is detected.
- the detection of the approximation takes place with the photodiode 14 'shown in FIG. 4, but with the reflected, weak and short laser pulses.
- the laser is preferably pulsed for ambient light or ambient light to be able to suppress as far as possible penetrates the receiver. This is very possible by using high pass and in the receiver electronics Low pass filter or band pass filter can be installed, which only the pulse frequency of the laser. Further, only the strong optical filters desired wavelength of the optical response of the optical by the laser excited feature passed. All other wavelengths will be suppresses, especially the laser wavelength itself, which in most Cases in the recipient itself. Only with an answer on the same Wavelength, the laser wavelength must of course be transmitted. In in this case the measurement is delayed by the optical response of the Recognize feature, that is after the end of each laser pulse observed whether light from the feature is still recognizable during the pause.
- the signals are also transmitted via averaged several laser pulses. This is preferably done in one Microprocessor, after previous analog-digital conversion.
