摘要
提出了一种条纹移动及形状变化都能预先设定的图案可控动态莫尔全息图的设计方法和制作技术。这种图案可控动态莫尔全息图能够产生旋转、放缩、变换等动态效果。给出了详细的理论分析和实验结果。它是一项非常实用的技术 ,用该技术制作的全息图防伪能力显著提高 。
A design method of pattern-controllable dynamic moire holograms that the strips moving and shapes changing can be pre-determined is presented. The dynamic effects produced by this kind of hologram are rotation, expansion, contraction, transformation, etc. The theoretical analysis and experimental results are given. This technology is feasible and practical. The anti-counterfeit capacity of the hologram manufactured is dramatically enhanced, and the hologram is easy distinguished.
