我国从八十年代中期(1987年左右)开始了激光模压全息技术的研制[1]。由于激光全息标识不能简单地利用普通的照相和印刷的方法复制;而且随着模压全息工艺的出现,使得低成本大批量制造全息图得以实现,因此激光模压全息图很快在防伪安全方面获得了应用。光学技术用于防伪,主要是利用光与物质相互作用时产生的散射、反射、透射、吸收、衍射等基本规律,获得某种特殊的视觉效果,例如多层光学介质薄膜结构、光栅结构等。但是,随着模压全息技术的迅速普及,使模压全息防伪标识的伪造技术也得以蔓延,从而降低了模压全息标识
China from the mid-eighties (about 1987) began the development of laser-molded holographic technology [1]. Because laser holographic marking can not be simply copied using conventional photographic and printing methods, and laser-embossed holograms are quickly gained in security as the advent of embossed holographic processes enables low-cost, mass-produced holograms to be realized application. Optical technology is used for anti-counterfeiting. It mainly uses the basic laws of scattering, reflection, transmission, absorption and diffraction generated when the light interacts with the material to obtain a special visual effect, such as a multi-layer optical film structure and a grating structure. However, with the rapid popularization of embossed holographic technology, the forgery technology of embossed holographic anti-counterfeit labels has also been spread, thus reducing the embossed holographic label
