Laser holographic anti-counterfeiting technology

Holographic anti-counterfeiting is a new type of anti-counterfeiting technology developed by laser holographic technology. With the progress of other anti-counterfeiting technologies, holographic anti-counterfeiting has also been developed and applied. Laser anti-counterfeiting, also known as laser anti-counterfeiting, or laser holographic anti-counterfeiting. Laser anti-counterfeiting technology includes three aspects: laser holographic image anti-counterfeiting, encrypted laser holographic image anti-counterfeiting and laser lithography anti-counterfeiting technology.

Laser holographic anti-counterfeiting technology is a three-dimensional photographic technology developed rapidly after the advent of lasers in the 1960 s. "Holographic" means "all information", that is, compared to ordinary photography only records the light and dark changes of the object, laser holography can also record the spatial changes of the object.

laser holographic anti-counterfeiting technology including:

1. Four-dimensional holographic dynamic anti-counterfeiting: Four-dimensional holography is composed of hundreds of 10. of two-dimensional digital pictures, holograms can not only record and reflect the three-dimensional spatial characteristics of the target, but also show the process of the target changing over time, and its anti-counterfeiting performance is extremely high.

2. Three-dimensional dot matrix anti-counterfeiting: Each point of the three-dimensional dot matrix hologram is a point hologram, which can express the sense of spatial depth and realize the real three-dimensional display in the virtual space. It can realize true color three-dimensional display for any three-dimensional data, and its anti-counterfeiting performance is extremely high.

3. Lithography dot matrix anti-counterfeiting: lithography dot matrix anti-counterfeiting technology refers to the arrangement, distribution and direction of its grating dot matrix controlled by the computer, which can produce dazzling color changes and dynamic patterns with the change of observation angle, also known as grating dot matrix anti-counterfeiting technology.

4. True three-dimensional anti-counterfeiting: True three-dimensional anti-counterfeiting hologram is a three-dimensional hologram in the real sense made by using a real carved three-dimensional model. This is different from the method of layering several 2D patterns to obtain three-dimensional (2D/3D), and its image is more real and three-dimensional.

5. Moiré encryption anti-counterfeiting: Moiré encryption is to make a predetermined pattern or text into a special computer Moiré code, and use a special decoder to detect the authenticity of the mark.

6. True color anti-counterfeiting: True color anti-counterfeiting label is to use the principle that each pixel of true color in the image is divided into three primary color components: R, G and B, and each primary color component directly determines the intensity of its primary color to produce a simulated real color label.

Laser encryption anti-counterfeiting: laser encryption anti-counterfeiting label is the use of optical technology to store text or some image information in a certain point or a certain area of the hologram. In normal observation, this information does not appear. When irradiated with a laser pointer, people can see the stored information with the aid of sulfuric acid paper or white paper.

8. Optical miniature anti-counterfeiting: the predetermined text or graphics with holographic microfilm technology embedded in the image, its visibility must be more than 100 times the magnifying glass identification. The minimum word height can reach 0.05mm.

9.2D/3D anti-counterfeiting: This technology can achieve multi-color, multi-level, layer and layer overlap and cross, with depth of field or gradient depth of field and real three-dimensional sense. Color gradient, pattern three-dimensional dynamic effect.

10. Pattern change anti-counterfeiting: pattern change (change) anti-counterfeiting, also known as dual-channel or multi-channel anti-counterfeiting, refers to the change by observing the angle of the pattern, you can clearly see two or more superimposed on the hologram at different angles One of the patterns.

Interference fringe anti-counterfeiting: interference fringe anti-counterfeiting label refers to the use of random fringe interference technology in the production of holographic anti-counterfeiting labels, which produces random interference patterns on the hologram. This pattern has obvious characteristics and cannot be repeated.

12. Speckle holographic anti-counterfeiting: Speckle holographic anti-counterfeiting technology (dynamic speckle anti-counterfeiting technology) is the use of laser to produce speckle, at the same time through the unique invention patent technology to control the shape, size and arrangement of speckle, so that the pattern formed can produce dynamic, three-dimensional and other holograms to show the characteristics.

13. Optical lens anti-counterfeiting: optical lens anti-counterfeiting is the use of the company's invention patent technology-three-dimensional dot matrix anti-counterfeiting technology principle, in the plane film to form a series of three-dimensional lens array, its size and focal length adjustable. There is a significant sense of three-dimensional and transformation to give a strong visual impact, anti-counterfeiting effect at a glance.

14.360-degree anti-counterfeiting: 360-degree anti-counterfeiting technology hologram is based on the core technology of our company's digital holographic display-holographic pixel, and further developed a future-oriented display holographic technology.
