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.
