| Abstract: | 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. |
