【Abstract】 In recently years,the laser holography techniqu es have achieved great developments in the anti counterfeiting fields. But ther e are several questions in anti counterfeiting quality of holograms. In this pa per,we analyse some hologram counterfeiting methods and present relavant securi ty and protection measures for counterfeiting in laser holography anti coun terfeiting applications,which can make progresses for laser holography anti counterfeiting technique and remain laser holography industries invincib le position.更多还原
