Description
Technical field
The utility model relates to a kind of testing instruments that relevant departments such as public security, frontier inspection, bank, the tax use that are used for, and this instrument is used in particular for the correction adulterium verification of traces and the anti-counterfeit recognition of bill, certificate, document.
Background technology
Most materials can be excited down in the irradiation of the light of some special wave band (may be visible light, also may be ultraviolet, invisible light such as infrared) and give off the light of another wave band, promptly produce fluorescence phenomenon.Two objects if send the fluorescence of different color (wave band), just can illustrate that the two is not material of the same race (material perhaps of the same race but state difference) under same light source irradiation.Note these fluoroscopic images with regard to the condition that provides the foundation for examination different material (or state).
Traditional file tester is that a cover is integrated in the photographic means in the casing, and its basic structure as shown in Figure 1.Mainly comprise camera or camera 10, camera lens 11, optical filter 12, alternative light source 13 these several big parts.Sample 1 (such as a check) is placed on the case inner platform.Use the light of different-waveband to go to shine it, can produce the fluorescence of different-effect (color, intensity) or not produce fluorescence.Optical filter 12 is mainly used to stop or reduces the directly light from radiation source of reflection of sample, and sees through the sample emitted fluorescence.Attempt carrying out multiple combined imaging, just might take the tangible fluorescent characteristics picture of this sample by camera with the irradiates light of different-waveband and the optical filter 12 of different-waveband.Be coated with by certain correction fluid such as this check and correct one's mistakes, be coated with reform the sanction so and will demonstrate the fluorescent characteristics that is different from former ticket, be easy to be found.
Traditional file tester mainly contains following shortcoming:
1, sample collection breadth is little.Irradiates light only reaches certain intensity of illumination on sample, could produce detectable fluorescence intensity.So have only the effectively imaging in limited sample zone of limited irradiates light concentration of energy.Traditional file tester can only be got the regional imaging of about 1/4A4 breadth usually, is exactly this reason.
2, uneven illumination is even, and yielding distortion.Traditional file tester is owing to shine with pointolite, and illumination is inhomogeneous usually in irradiation face scope.And in literary composition inspection business, need the fluorescence image signal gathered with the multiple light courcess photographic means often again a little less than, when uneven illumination was even, the fluorescence phenomenon on figure just had bigger difference, image definition can be subjected to bigger influence.Splicing again after the image of large format just needs to divide several illuminations to take pictures, this brings very big inconvenience to operating personnel, and simultaneously, image is easy to distortion, distortion.
3, the restriction of light source wave band.The light source of traditional file tester uses the white light source of a high power high luminance, isolates the wave band of needs as illumination light by some light source optical filters (bandpass filter) then.Though the total light source power of this mode is very high, each wave band all only occupies the sub-fraction of gross energy in fact, and the luminous energies of the overwhelming majority all are wasted all the time.Secondly because to be subjected to instrument internal space constraint, light source optical filter can only be with limited several, this can make some materials owing to the irradiation of failing to be subjected to the characteristic wave bands light source can not show due characteristic fluorescence phenomenon.All bad in ultraviolet band institute's common intensity of isolated light and purity at last, so the imaging capability of traditional file tester Ultraluminescence is not good usually.
The utility model content
Fundamental purpose of the present utility model is to provide a kind of brand-new scan-type file tester.
To achieve these goals, the technical solution adopted in the utility model is: a kind of scan-type file tester includes: electronic control translation stage is connected with image-generating unit on this electronic control translation stage; Image-generating unit, this image-generating unit comprises light source and camera head, and camera head is positioned at the image-generating unit lower position, and light source is positioned at the image-generating unit top position; The sample window is positioned at the image-generating unit top, and the sample window is a transparent window, and it presses close to the light source position of image-generating unit; Be used to control the system control module of electronic control translation stage and image-generating unit, this system control module connects electronic control translation stage and image-generating unit.
Wherein, this system control module comprises scanning shoot control module and image mosaic processing module.
This electronic control translation stage is one dimension or two-dimentional electronic control translation stage.
This sample window top is provided with cover plate.
This light source is two LED lamp bar or cold cathode fluorescent lamp placed side by side.
This camera head is camera or digital camera.
The beneficial effects of the utility model are: the utility model proposes with the antipodal thinking of traditional file tester and improve their shortcoming comprehensively, realize a kind of file tester of brand new.The tradition file tester requires to try one's best in big scope intraoral illumination imaging, and the utility model is then realized all fluorescence imagings of even high brightness by the mode that sample is adopted local microcell press close to illumination and shooting; The tradition file tester adopts light source and the fixing structure of imaging device, and the different microcells that the utility model is transferred to sample successively by motor-driven light source and taking module translation are taken, and all microcell pictures are spliced automatically to synthesize a width of cloth large format sample full figure (can reach more than the A4 breadth) then; The tradition file tester is pursued the lighting source of high-power and high-luminance, so that isolate single-range illumination light of sufficient intensity, the utility model then adopts brand-new standard sources to plug structure, the light source of each wave band all is independently with using with inserting, so use the good low energy consumption light source of common monochromaticity (as LED and cold cathode luminous source) to get final product, and light source wave band quantity is unrestricted again.
