激光全息术是继激光器于六十年代问世之后迅速发展起来的一种立体照相技术,在图像三维显示、干涉计量和无损探伤等领域得到了成功的应用。七十年代,随着激光全息图能大批生产,亦即模压全息技术的发明,激光全息术成为一种防伪新手段,先后被应用到信用卡、证件和有价证券的防伪范畴。由于激光全息图像的强烈视觉冲击效果,以及信息显示大容量、多通道和色彩丰富,激光全息迄今为止仍是国际上用于公众防伪的主流技术,其便于识别、难于仿制和易于批量生产的特点很难在短时期内被其它防伪技术所替代。激光全息术的信息记录材料是指能批量生产的承载彩虹全息图或者反射全息图的材
Laser holography is a kind of stereo camera technology developed rapidly after the laser was introduced in the 1960s. It has been successfully applied in the field of 3D image display, interferometry and non-destructive testing. Seventies, with the laser hologram can be mass-produced, that is, the invention of embossed holographic technology, laser holography has become a new anti-counterfeiting means, has been applied to credit cards, certificates and securities security areas. Due to the strong visual impact of laser holographic images and the large volume, multi-channel and color richness of information, laser holography has so far been the mainstream international anti-counterfeiting technology that is easy to identify, hard to copy and easy to mass-produce It is difficult to be replaced by other anti-counterfeiting technology in a short period of time. Laser holographic information recording material refers to a mass-produced material carrying a rainbow hologram or reflective hologram
