无钥匙位相型双图像莫尔编码技术

Encoding Double Images Using Non-key Phase-only Moire Method

根据光的衍射原理和莫尔图像编码原理 ,实现了无钥匙位相型双图像莫尔编码技术。用该技术制作的位相板可以在不同的衍射级上分别再现出 2个被编码的图像和 3个模板的图像 ,它们在空间上是按一定的顺序排列的。这一特性用其他技术难以模仿。该技术可应用于防伪领域 。

According to the theory of light diffraction and that of moire image encoding,a new technology of double image encoding using non key phase only moire method is presented in this paper.The unique reconstruction nature of the non key moire encoded plate manufactured with this method can not be imitated with other technologies.If it is used in the anti counterfeit domain,the technology can dramatically enhance the anti counterfeit capacity of products.
