摘要
利用具有点光源特征的参考光波产生等厚干涉条纹,作为激光彩虹模压全息防伪标识的随机背景条纹,成为一种新的加密机制,其特点是难以仿制,不增加成本,并可用于一线防伪.
A point-source reference wave is used to produce interference fringes ofequal thickness. These fringes act as the random background on the laser rainbowembossed holographic labels for anti- counterfeiting. This method becomes a newway to code on holograms. The features of this method are that it is nearlyimposslibe to imitate the labels after using this method, it would not cause anyextra price to the product,and it could be used in the 'frontline' of anti- counter-feiting.
