Description
Technical field
The utility model relates to a kind of high resolution digital image harvester, is specifically related to the incorgruous light source image sensor of contact of a kind of special collection bank note and bank money.
Background technology
Currency security relationship is to the financial security of whole country, and the criminal offence of counterfeit note and bank money acts recklessly always, and fraud mode emerges in an endless stream, and fraud means are also day by day brilliant.Paper money discrimination, as the gordian technique of hitting counterfeit money manufacture, more and more receives publicity.At present, authentication detection technology mainly relies on the multispectral image that gathers and analyze bank note.The module that conventional image collecting device is made up of light source, sensor unit and the optical lens of different wave length, as contact-type image sensor (CIS).Such sensor can gather high-resolution colour picture, gray level image, infrared light image and the ultraviolet light image of bank note, and these images have comprised bank note overwhelming majority anti-counterfeiting information, can reach certain false distinguishing object by analyzing.But due to the lifting of fraud level, the anti-fake effect of most of false proof point weakens gradually.At present, color shifting ink and two false proof points of stealthy denomination numeral still have very strong antiforge function, and existing harvester can not collect these anti-counterfeiting information in the middle of image.

Utility model content
The utility model provides the incorgruous light source image sensor of contact of a kind of special collection bank note and bank money, and can overcome existing banknote image harvester can not collect the technical deficiency in the middle of image by color shifting ink and two important anti-counterfeiting information of stealthy denomination numeral.
The utility model solves the technical scheme that its technical matters adopts: a kind of incorgruous light digital image collecting device, by Power supply, comprise housing, array board, sensor array, printing opacity prism, light permeable protection and the first light source and secondary light source, the upper base surface of described housing and the lower surface of described array board are fixed, the open top of described housing, in described case top, be covered with light permeable protection, on array board, be equipped with sensor array, sensor array receiving end vertically upward, the upper end of described sensor array is fixed with printing opacity prism, described the first light source and secondary light source are installed in housing, light permeable protection described in described the first light source and the equal tilt alignment of secondary light source, angle between described the first light source and described light permeable protection is greater than the angle between described secondary light source and described light permeable protection, described the first light source is same position at light incidence point and the secondary light source of described light permeable protection at the light incidence point of described light permeable protection, described sensor array receiving end is aimed at the light incidence point of the first light source at described light permeable protection.The beneficial effects of the utility model are, except collecting the anti-counterfeiting information such as bank note pattern, texture, phosphor pattern, colorless fluorescent fiber, light and shade watermatk, infrared printing ink, the anti-counterfeiting information that two traditional harvesters of color shifting ink and stealthy denomination numeral cannot can also be gathered is presented in multispectral image, can collect visible ray, infrared light and ultraviolet light image under two kinds of different viewing angles, for paper money discrimination analysis provides more comprehensively anti-counterfeiting information.
As preferably, described light permeable protection is protecting glass, and described printing opacity prism adopts biserial light-guiding pillar, and described the first light source and secondary light source are LED.Above technology is comparatively ripe, is widely used, and cost is lower, is applicable to extensive use.
As preferably, the angle between described the first light source and described light permeable protection is 75 degree, and the angle between described secondary light source and described light permeable protection is 45 degree.Arrange like this than being easier to determine focus, the light of corresponding reflection and the mobile phone of signal are comparatively accurate.
As preferably, the level height of described secondary light source is higher than the level height of described the first light source.
The beneficial effects of the utility model are: the utility model is except collecting the anti-counterfeiting information such as bank note pattern, texture, phosphor pattern, colorless fluorescent fiber, light and shade watermatk, infrared printing ink, the anti-counterfeiting information that two traditional harvesters of color shifting ink and stealthy denomination numeral cannot can also be gathered is presented in multispectral image, can collect visible ray, infrared light and ultraviolet light image under two kinds of different viewing angles, for paper money discrimination analysis provides more comprehensively anti-counterfeiting information.
