- Each detector set is defined by a photodiode, a filter and a lens, said set being duly encapsulated.
- the recognition of the documents can be done by reflection, so that the light emitted by the security mark of the document to be recognized is detected by the detector assemblies on the same face of laser light incidence, or by transmission, so that the light emitted by the laser passes through the document to be recognized, exciting the security mark, being detected by the detector assemblies on this second face.

- BACKGROUND OF THE INVENTION According to the devices for the recognition of documents, existing in the market, we can make a first division in relation to the material application of the same, and, thus, we can refer to those devices for the recognition of application tickets in multitude of establishments, and those basic application devices in banking entities.
- the authenticity check test apparatus comprises a lamp and a filter that lets a certain band of waves pass to a crystal, positioned at 45 s with respect to the incidence of the waves, which transmits 50% to the document to be authenticated. , previously, going through a filter, so that the reflected waves pass through said glass to a filter and to the detector.
- This document describes a document recognition system, being of the type of systems used for the recognition of documents provided with a security mark, whose security mark is defined by an excitable substance when emitting on it a light coming from the corresponding light source, so that the system comprises a light source defined by a modulated frequency diode laser set and at least two detector sets of the reflected light, by reflection or transmission, by the excitable substance relative to the mark of security of the document to be recognized, each detector set being associated with an electronic signal filtering and treatment system and in turn, with a single microprocessor.
- the filter to eliminate unwanted radiation is very low cost, since it eliminates radiation of 1000 orders smaller than magnitude.
- each detector assembly of the light emitted, by reflection or transmission, of the excitable substance relative to the safety mark is defined by a photodiode, a filter and a lens, properly encapsulated.
- each detector assembly of the emitted light, by reflection or transmission, of the excitable substance relative to the safety mark is integrated in a body that groups all the detector assemblies of the emitted light, so that all the detector assemblies they are oriented to a point, as can be seen in figures 4, 5 and 6 of the designs.
- the light source defined by a modulated frequency diode laser assembly excites, in a certain wavelength, the substance relative to the security mark of the document to be recognized, emitting light in various wavelengths and being these detected by the detector sets, with respect to certain points of the characteristic curve of the generated wave, so that once treated electronically, the microprocessor performs the analysis and pertinent operations to be compared with the set of values stored in its memory, in order to determine if the recognized document is authentic or false .
- the characteristic curve of the generated wave is analyzed by the number of detector sets, being able to perform different comparison methodologies.
- the relative intensities of the emissions at different wavelengths ⁇ -, ⁇ 3 , ⁇ 5 ..., or with the definition of a threshold the analysis of the existence or non-existence of emission at specific wavelengths can be analyzed i, ⁇ 2 , ⁇ 3 , ...; these wavelengths for both cases being determined for each of the detector sets by the filters integrated in the detector assembly.
- the document recognition system incorporates a presence detector determining the positioning of the security mark in the document to be recognized, allowing to know the area it recognizes and its position in the document. With the arrangement of the elements comprising the document recognition system, the detection path is very short, obtaining a greater optical tolerance with the distance of the ticket, and obtaining a small size and cost equipment.
- the described optical composition allows the diode laser, as well as the detector assemblies of the light reflected by the excitable substance of the security document to be very close to the document itself, that is, that the optical path is very small, with which prevents the light emitted by the substance from dispersing (as can be seen in Figures 1 and 2).
- this descriptive report is accompanied by a set of drawings, whose figures are illustrative and not limiting , the most characteristic details of the invention are represented. BRIEF DESCRIPTION OF THE DESIGNS.

- the document recognition system comprises a modulated frequency diode laser 1, whose light is emitted towards the document 2 to be recognized, which is provided with a safety mark defined by an excitable substance in a band of certain length, light being emitted in various wavelengths, and which is detected by at least two detector sets with respect to certain points of the characteristic curve of the generated wave.
- the filter to eliminate unwanted radiation is very low cost, since it eliminates radiation of 1000 orders less than magnitude.
- the filter used must filter a lot of unwanted wavelength, so the effective power is very small compared to the real one of the lamp, not as in the laser that the Real is 99% effective. With all this you get to have a very low consumption of the 3W device being a 5W stand-by video.
- the detector sets 3 consist of a photodiode 4, a filter 5 and a lens 6, so that the light emitted by the excitable substance relative to the safety mark, detected by the detector sets 3 is processed analogically by means of a filter 7 and an amplifier 8 and sent to a microprocessor that incorporates the system.
- the microprocessor calculates after the relevant operations the signal difference analyzed by the sets detectors to be compared with the value stored in its memory in order to determine if the recognized document is authentic or false, being able to observe in figure 3 of the designs a series of points at which the wavelength measurement materializes, referred to the characteristic curve of the generated wave.
- the system can incorporate a variable number of sets 3 detectors, incorporating at least two sets of detectors.
- An important advantage of the system is that the components of the optical composition have a reduced cost and they can be integrated into an apparatus of very small dimensions, allowing its application in all types of establishments, while presenting a total reliability.
- the system can act by reflection, so that the light emitted by the excitable substance of the document to be recognized is on the same face as the excitation laser light, or with the appropriate power both pass through the bill, and detected by the sets detectors placed next to the laser excitation light, or the system can act by transmission, so that the light emitted by the diode laser passes through the document and the excitable substance of the document to be recognized is excited, being analyzed in this second face
