Abstract

The utility model provides a novel anti-counterfeiting device, which belongs to the technical field of optical counterfeiting prevention and is composed of a decoding sheet and a coding speckle sheet. The decoding sheet is used for distributing specific random black spots which are formed by the image formation of a random laser speckle field or a white light speckle field, and contraposition lines are arranged around the decoding sheet. The structure of the encoding speckle sheet is the same as that of the decoding sheet, and the circumferences of a group of speckle patterns which look irregular are provided with contraposition lines which are designed in advance. But the encoded image information is contained in the speckle field of the sheet. The novel anti-counterfeiting device has the advantages of good anti-counterfeiting effect, low cost, and convenient operation and can be extensively applied to anti-counterfeiting marks of the fields of laser, hologram, etc., of commodities.

Description

一种新型防伪装置 A new type of security device

本实用新型提供一种新型防伪装置,属光学防伪领域。 The present invention provides a novel security device, belongs to the field of optical security.

假冒伪劣是仅次于贩毒的世界第二大“公害”,给国家、企业和消费者都带来巨大的危害和经济损失。 Fake is second only to drug trafficking in the world's second largest "public nuisance" to the state, businesses and consumers have brought great harm and economic loss. 因此,打假防伪是关系到国计民生的重要大事。 Therefore, the security crackdown is related to the national economy and an important event. 利用各种有效可靠的防伪技术,主动防范,是解决假冒伪劣问题的关键。 Using a variety of effective and reliable anti-counterfeiting technology, active prevention is the key to solve the problem of counterfeiting. 目前国际上采用的防伪技术有14类,其中激光全息标识是防伪技术最成功的范例之一。 Anti-counterfeiting technology currently used internationally in 14 categories, including laser holographic anti-counterfeiting technology logo is one of the most successful examples. 但目前使用的激光防伪装置由于国内厂家增多,个别厂家受利益驱动,出现了防伪商标被仿冒现象。 However, laser anti-counterfeit devices currently in use due to increased domestic manufacturers, driven by the interests of individual manufacturers, there have been anti-counterfeit trademark counterfeiting phenomenon. 防伪企业要真正为名、优、新、特产品及企业保驾护航,就必须不断推出新技术,充实防伪产品的技术含量,使造假者无能为力。 To really the name of the security company, excellent, new, special products and protect the enterprise, we must continue to introduce new technology to enrich the content of anti-counterfeiting technology products, so counterfeiters do nothing. 利用编码散斑片制成防伪标识国内外未见报导。 Speckle sheet made using the coded security identification abroad been reported.

本实用新型提供一种防伪效果好,成本低,利用编码散斑技术的新型防伪装置。 The present invention provides a security effect is good, low cost, the new security device using the coded speckle technique.

激光照明物体漫反射表面时,在物体前面的空间会产生无数随机分布的亮斑和暗斑,称为散斑。 When the laser illumination of diffuse reflection surfaces, the space in front of the object will produce numerous randomly distributed bright spots and dark spots, called speckle. 当激光照射到物体表面时,物体表面上的每一个点(或面元)都可视为子波源,它们都要散射光,离表面某一距离处得到的光波场是由许多来自表面的不同面元的光波叠加而成,诸子波干涉的结果,就产生空间无规分布的散斑图样。 When laser light is irradiated to the object surface, every point (or bin) on the surface of an object can be regarded as wavelet sources, which have scattered light obtained from the light wave field at a distance from a surface is made from a number of different surface superposition of light waves bin, Zhuzi result of the interference wave, the spatial speckle pattern generated randomly distributed. 散斑是一种随机光强度分布,具有颗粒状的外貌,服从统计规律。 It is a random speckle light intensity distribution having a granular appearance, obey the laws of statistics.

散斑是高度随机分布的复杂光栅。 Speckle is a complex grating height randomly distributed. 对于一个确定的散斑图,采用信息处理技术可以将文字、图形编码在散斑图中。 For the determination of a speckle pattern, using information processing techniques may be text, graphics, coding in the speckle pattern. 由于散斑图的随机性,编码散斑图中看不到被编码的文字或图形。 Due to the randomness of the speckle pattern, speckle pattern is not visible coding encoded text or graphics. 利用上述特点,可以制作编码散斑隐型密码。 With the above features, it can produce speckle invisible encoded password. 解码片也是一个无规散斑图。 A decoded tile is random speckle pattern.

本实用新型的新型防伪装置是由解码片和编码散斑片构成,解码片是对随机的激光散斑场或白光散斑场成像形成一特定的随机的黑点的分布,在其四周有对位线。 The present invention is a novel security device comprises the decoding and encoding of speckle sheet, decoding a particular sheet is formed of a random distribution of black dots random speckle field of laser speckle field imaging or white light, in which there are four weeks bit line. 其编码散斑片是将解码片和需要编码的图像扫描到微机里,移动需编码的图像重叠到解码片图像上。 Which encodes the decoded speckle sheet is a sheet to be coded and the image scanning to the microcomputer, the movement to be encoded image is superimposed on the decoded image slice. 根据图像重叠部分增减原理,形成的编码散斑片。 The image overlap portion changes in principle, encoded form of speckle. 编码散斑片结构上与解码片相同,看似一群无规则的散斑图,四周有事先设计好的对位线,但该片的散斑场中包含有被编码的图像的信息。 Coding decoding sheet of speckle same structure, a group of seemingly random speckle pattern, surrounded by the bit line pre-designed, but the speckle field comprising an image sheet in the encoded information.

利用彩印技术将编码散斑片印在商品的包装盒上,盒中附有解码片,需要检验商品的真伪时,将解码片按对位线重叠在商品盒的编码散斑图上,轻轻移动解码散斑软片,即可看到被编码的图像。 Encoding techniques using speckle color printed on the packaging sheet goods, the decoding cassette with sheets, need to verify the authenticity of goods when the sheet by decoding the bit line coding speckle pattern superimposed on goods boxes, light decoding moving film speckle light, to see the image is encoded. 如果在彩虹全息图某分层上拷贝上编码散斑图,检验商品真伪时,只要将解码片按对位线重叠在全息标识上,轻轻移动解码片,即可看到被编码的图像,从而制作成带散斑隐性密码的全息标识。 If the copy speckle pattern encoded in a hierarchical rainbow holograms, when testing the authenticity of goods, as long as the sheet according to the decoded bit line superimposed on the hologram identification, gently move the sheet decoding, the encoded image can be seen order to prepare the holographic label with speckle hidden password.

本新型防伪装置防伪效果好,成本低,便于操作。 This novel anti-counterfeit security device good effect, low cost, ease of operation.
