Study On The Anti-counterfeiting Principle And Detecting About Up-conversion Material

The realization of the advanced anti-counterfeiting function of infrared (IR) up-conversion material is the development of weak spectrum detecting system. An imperfect detecting method would be an obstacle in the application and the expansion of IR anti-counterfeiting material. Though the liveliness of anti-counterfeiting material is obviously, the IR anti-counterfeiting products haven’t been discovered on the market. This paper discussed the anti-counterfeiting technology of IR up-conversion material, and scooped out its anti-counterfeiting potential from the abundant spectrum information. The application of defending forgery and its detecting method were presented and the numerical code detecting system was designed. The meaningful quest for the technical development was done.At first, the article summarized the research background of IR up-conversion material and the current situation of studies about it at home and abroad, also analyzed the foreground of application about it. Then the article briefly introduced luminescent theory of IR up-conversion material and analyzed the anti-counterfeiting principles of this material. There was brought forward some all-around measurements of defending forgery.Finally the article discussed the detecting technique of IR anti-counterfeiting material in detail, which included generic technique and advanced technique and emphasized the development of the software and hardware of the numerical code detecting system which included the infrared detector, signal transmission, the adjusting of low signals, displaying code and so on. The article spoke at length about the method of reducing the noises in collecting of the weak light signal and anti-interference processing. The instrument of detecting password can test and display the defending code.The key point of the article placed on the detecting technique. According to the practical study of anti-counterfeiting technology, some useful proposals were also put forward in the article.
