摘　　要：文章利用随机散斑对防伪标识进行鉴别真伪。以彩虹全息为理论基础制作真彩全息防伪标识,利用掩模图,制作全息母版,利用该母版得到复制品;将复制品与母版进行对比,在显微镜下可以发现,复制品上的散斑分布、形状大小与母版基本一致。于是,利用随机散斑对防伪标识进行真伪鉴别是可行的。In this paper,the random speckle is used to distinguish the false proof labels.With the rainbow hologram as the theoretical basis,true color hologram anti-fake labels are made.Mask pattern is used to make hologram mastering mould,through which copying product is obtained.The copying product is compared with the mastering mould.Under the microscope,we can find the distribution and size of the speckle similar to the ones of the mastering mould.Therefore,it is feasible to use random speckle to distinguish the authenticity of the anti-counterfeit mark is feasible.
