Problems solved by technology

However, various existing anti-counterfeiting treatment methods have relative detection methods for different anti-counterfeiting features, and generally require different instruments to display features with specific wavelengths of light
And when using the existing detector, the user is directly exposed to IR or UV light source, which will cause harm to the human body
In addition, after the test is performed, the relevant data of the test certificate cannot be saved

Embodiment Construction

[0016] The FDD (Forged Document Detector) of the present invention is a device that can continuously check various physical parameters and security features of documents under the electromagnetic radiation in a wide wavelength range. These electromagnetic radiations include ultraviolet, visible and infrared light, These lights may be invisible to the naked eye or they may cause harm if they are directly exposed to the human body. The counterfeit detector can inspect documents using a variety of light sources that can be selected, such as: color imaging with white light; visible fluorescence imaging with UV; and visible monochromatic images when illuminated with infrared light. Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] see 2A to 2D , The counterfeit detector of the present invention includes two main units: a light-emitting unit and an imaging unit, wherein the light-emitting unit can...

Abstract

The invention relates to a false element detector, which uses digit video flow technique to check and record safe certification or matter, wherein said method comprises: input unit providing a select interface to user; processor controlling the lighting unit via the select signal sent from input unit; lighting unit providing the light of light source to the image unit; and image unit for obtaining the image of certification or matter. The image unit comprises low-reflective glass plate, cover plate, optical element and image sensor; the invention also comprises display element to display obtained image. The invention can effectively avoid light leakage of between indoor room and external condition of detector, to avoid light hurting people; and it contains light resources at different wavelengths as UV, virtual light and IR, and uses digit video flow technique to check and record relative information of certification.

Description

technical field [0001] The invention relates to the field of counterfeit detection, in particular to a counterfeit detector for checking and recording secure documents or objects by utilizing digital video streaming technology. Background technique [0002] In recent years, some unscrupulous traders have forged or counterfeited currency and documents such as passports, ID cards, CDs and artworks in order to obtain improper benefits, in order to earn a lot of money, which has harmed the interests of the victims and caused adverse social order. influences. For this reason, various technologies are used to prevent forgery of the documents when they are manufactured. The use of UV inks, IR inks, watermarks, etc. to make identification marks is a common method for anti-counterfeiting processing. These marks must be visible under certain visible or invisible light. [0003] In order to check the authenticity of documents, many places now use detectors to identify documents, suc...
