Currently the most popular laser holographic technology

Laser holographic projection technology is to process the transmitted image information by numerical technology, transform the long-wave part of the image into phase modulated hologram (holographic grating), and realize the projection by diffraction optics. Holography can be divided into physical holography, digital holography and computational holography. Among them, CGH technology can use a camera to track the changes in the Angle of the human eye, then calculate the actual hologram based on relevant technology, then project the stereo image of the left and right eye retina of the human eye through a special display screen. In this way, the holographic projection seen by the human eye is not that different from the real thing.

At present, as the crystallization of high and new technology, laser holographic anti-counterfeiting sign is a modern Laser pointer application technology achievement that has been widely concerned at home and abroad in recent years. With unique anti-counterfeiting function, can increase the beauty of the product. Color flash effect favored by consumers. Internationally recognized as the most advanced, the most economic anti-counterfeiting marks, can be widely used in light industry, medicine, food, cosmetics, electronics and other industries of famous quality trademarks, securities, confidential documents, high-grade crafts, etc. Compared with printed trademarks, it has unique advantages and charm.
