Holographic anti-counterfeiting
Holography is a technique of recording and reproducing the true 3d image of an object using the principles of interference and diffraction. The first step is to use the principle of interference to record the light wave information of the object, that is, the shooting process. The second step is to use the diffraction principle to reproduce the light wave information of the object, which is the imaging process. According to the different USES divided into: holographic anti-counterfeiting technology, display holographic technology.

Advantages of holographic technology: the reconstructed three-dimensional image is conducive to the preservation of precious art materials for collection; When shooting, each point is recorded on any point of the hologram; Holographic photographs of the scene three-dimensional sense, vivid image, laser can be displayed in various exhibitions.
