从信息论角度看待光学防伪技术

Optical anti fake technology from the perspective of information theory

本文基于信息论的角度浅谈光学防伪技术,首先介绍了信息论和光学防伪系统的关系,随之简要介绍了现有的光学防伪技术,最后以光学全息防伪技术为例进行详细的分析。

The paper introduced the optical anti-Counterfeiting technology from the view of the elements of information theory. Firstly,the relationship between the elements of information theory and the anti-counterfeiting system was introduced. And then the up-to-date optical anti-counterfeiting system was summarized. Finally, as an example,the optical holographic anti-counterfeiting technology was analyzed in detail.
