-
摘要: 近年来,激光全息技术在防伪领域中已取得了巨大的进展,但在防伪性能方面仍存在不足,针对激光全息防伪应用中的仿冒问题,分析了其中的原因,并提出了相应的安全保护方法,从而能促进激光全息防伪技术的发展,使激光全息产业立于不败之地.Abstract: In recently years,the laser holography techniques have achieved great developments in the anti-counterfeiting fields. But there are several questions in anti-counterfeiting quality of holograms. In this paper,we analyse some hologram counterfeiting methods and present relavant security and protection measures for counterfeiting in laser holography anti counterfeiting applications,which can make progresses for laser holography anti-counterfeiting technique and remain laser holography industries invincible position.
