Dynamic and Full-Color Projective Imaging Technology

Two novel projective imaging technologies are introduced in this article. The projective images can be easily observed by public in reflection,or transmittion, or projection.The light sources can be mobile phone flash. One can observe not only the achromatic images, but also full-color ones, and even vivid dynamic amination. These technologies are based on the combination and coordination of reflection, interference and diffraction. The accurate control of microstructure origination and metallization process guarantees the high-level security feature. Coordinated with other first level security features such as holograph, demetallization and surface plasmon resonance, the novel projective imagine technologies can provide integrated authentication of high value documentation, and exhibit promising future in security threads, stripes and patches
