探索基于激光冲击波力学效应的无损三维高防伪标识的基本理论，建立一种与激光热效应完全不同的激光冲击波标识新技术，提出将灰度图像的重建技术和二进制编码技术应用到三维标识的识别上，建立一种新型高效的零件标识的检测和识别理论，并对标识的高防伪性能进行了研究。

The elementary theory of three-dimensional (3D) nondestructively anti-counterfeiting identifiers based on liquid crystal mask was explored and a new technology of creating by laser shock wave was set up, which differs entirely from marking by laser thermal effect. The depth information of 3D identifiers is acted as anti-counterfeiting information, and a new-type and high-efficiency theory of measurement and identification on 3D anti-counterfeiting identifiers by 3D identifiers' reconstruction and binary coding is established originally. The anti-counterfeiting properties 3D identifiers are studied, which is beneficial to design and manufacturing of anti-counterfeiting identifiers.
