3.3.1 Holographic anti-counterfeiting
Anti-counterfeiting is closely related to our life, the application of holographic technology in the field of anti-counterfeiting can greatly improve the anti-counterfeiting effect. The first product to feature a hologram as an anti-counterfeiting label was Johnny Walke Whishy, which saw a 45% increase in sales. In the 1990s, holographic anti-counterfeiting had its first heyday. Laser molding technology was widely used in the promotion of high-grade goods, the anti-counterfeiting and encryption of famous and high-quality goods or securities (such as credit cards, banknotes, passports and visas), as well as books, printing, printing and dyeing, decoration, commemorative stamps and advertising signs. The technology was introduced into China in the late 1980s and early 1990s. From 1990 to 1994, hundreds of production lines were introduced across the country.
Main holographic anti-counterfeiting technology.
1. Laser holographic identification positioning hot stamping technology
Holographic stamping principle is: on the hot stamping equipment by heating the hot stamping die to the hot melt glue line on the holographic stamping materials and separation layer heated to melt, under certain pressure, hot stamping material information layer holographic grating stripe and PET substrate separation, make the information layer and the aluminum foil adhesive steamed, together, to achieve a perfect combination.
2. Encryption technology on holographic signs.
The technology is to set special encryption mark in the anti-counterfeiting mark to enhance the anti-counterfeiting effect. The principle is that an encoder is added between the object and the holographic baseplate to distort the object light. Only with this particular decoder can the object be reproduced, otherwise only some speckle will appear. Therefore, the technology has a high anti-counterfeiting function, often used in general goods anti-counterfeiting.
3. BOPP laser holographic anti-counterfeiting shrinkable film packaging anti-counterfeiting technology.
This technology is a new anti-counterfeiting technology developed. Because the technology has special requirements for BOPP shrinkable film substrate, the purchase and development of BOPP production equipment is expensive, thus blocking the possibility and feasibility of counterfeiters from the source. In the production of laser holographic anti-counterfeiting shrinkable film, the wide-width holographic transparent molding technology is firstly combined with the anti-counterfeiting technology of encrypted holographic image, and the contradiction between hot pressing and thermal shrinkage of substrate is solved artfully. In use, two surfaces of BOPP anti-counterfeiting shrink film are provided with heat seal, which will be wrapped in the package as a whole; When unpacking the BOPP security film must be torn first, and this will destroy the integrity of the original security film. Because of the technical complexity, high anti-counterfeiting strength, fine technology and exquisite appearance of the anti-counterfeiting means, the laser holographic technology professional committee of China anti-counterfeiting industry association has given a high evaluation. The high price of BOPP production line and the complex processing technology of heat-sealed heat-shrinkable film, together with transparent holographic anti-counterfeiting images and secret microscale codes, make it extremely difficult for scattered small and medium-sized factories to fake.
3.3.2 Holographic storage
Laser holographic storage technology is a kind of mass storage technology which can parallel read/write, improve data rate and increase storage capacity.
Since the discovery of photorefractive effect in the late 1960s, holographic storage in photorefractive crystals has become a hot spot for a time. In 1975, RC Corporation of America reported the experiment of 500 holograms stored in 1cm lithium niobate crystal. In 1991, Northrop, Inc. stored and reconstructed 500 high-resolution military vehicle holograms with high fidelity in iron-doped lithium niobate crystals. In 1992, 1,000 pages of digital data were stored in the same lithium niobate crystal, and nothing was mistakenly copied to the digital computer's memory. In 1994, 10,000 holograms were recorded in a 1cm iron-doped lithium niobate crystal at the California Institute of Technology. That same year, a team at Stanford University stored compressed digitized image and video data in a holographic memory. IBM has also developed a flexible and stable high resolution automatic holographic storage system test bed. At present, China is mainly developing a method of using binary spatial light modulator to realize multi-gray-scale holographic storage, which can further improve the storage density and the transmission rate of readout data. Others are studying the content addressing function of volume holographic correlator, which can carry out association retrieval in parallel and fast, and has great potential for improvement.
Stanford University's HDSS Worm Demonstration Platform. In 2000, Stanford University developed a holographic optical disc storage system with high transmission rate and high capacity for DARPA's HDSS project, as shown in the figure below. The system uses IBM's ferroelectric liquid crystal spatial light modulator (FLC SLM) to record two-dimensional data. The highest resolution is 1 024×1 024 pixels, and Kodak's CCD is used as the detector. The resolution matches SLM and the maximum frame number is 1 000 FPS. Using the pulse frequency doubling Nd: YAG laser (wavelength of 532 nm) to record and playback, cd-rom installed on the precision of the aerostatic bearing, using holographic channel decoding precision of photoelectric shaft encoder system transmission rate can be up to 1 Gbits/s, use 1 write once read many times (WORM) to polymer as a storage medium, capacity is 120 GB. Since the storage capacity of thicker media (such as LiNbO3 crystals) is more affected by the dynamic range and noise of the medium than by multiplexing techniques, whereas that of thinner media (such as photopolymers) is not, the number of holograms that can be stored is largely determined by multiplexing techniques. Angular multiplexing, which is often used in thicker media, is not effective here, and other multiplexing techniques, such as shift or rotation multiplexing, are needed. This system uses speckle shift multiplexing.

Holographic memory is expected to store hundreds of billions of bytes of data (currently 640 gigabytes on optical disks), have high fidelity, transmit data at speeds equal to or greater than bit/s, and can randomly select a data page in 100 microseconds or less. At present, the research, development and industrialization of holographic storage technology are developing vigorously in China.
