Using holographic technology

by:LG Printing     2020-03-20
With the gradual recognition and acceptance of digital cameras, the digital camera market has expanded every day. The digital camera manufacturers have also developed new technologies or existing technologies. The digital camera field is maintained and upgraded. sony DSC in camera field- The F707 focusing mode uses holographic photography laser auto-focusing assistance. It is also said that holographic technology has been applied to the bottom holographic technology in the field of photography. There is a difference between holographic photography and traditional photography (Hologram)Gabe (Gabor) In 1948, the improvement of the image quality of the electron microscope was put forward, and its significance was to completely record Geber's experiment, which solved the basic problem of the invention of holography, namely, wavefront recording and reproduction due to the lack of bright coherent light sources (Laser) , Hologram imaging quality is poor 1962 with the advent of lasers Liz and upatknicks ( Leith and Upatnieks) The concept of carrier frequency is introduced into Geber holography, and off-axis holography is invented, which effectively overcomes the main problem of poor Hologram imaging quality at that time--- The three-dimensional object of the twin image was displayed as a hot spot in the research of holography at that time. The Imaging Science far exceeded the economic development at that time. The production and observation of the hologram was expensive. Holography became a synonym for the high cost to maintain the Actual Fantasy. 1969 Benton (Benton) Rainbow holography was invented to set off white light display feature holography three-dimensional display new climax rainbow hologram can realize white light display plane hologram and denissuk (Denisyuk) Compared with ordinary incandescent lamp, reflective hologram has the advantages of simple hologram processing process, easy copying, etc, the application of holography in the field of photography is far superior to that of ordinary photography. According to the principle of lens imaging, the light intensity distribution formed by projecting a three-dimensional scene onto a plane photosensitive bottom plate is recorded. The photo has no stereoscopic impression because the photo is seen from various angles. like exactly the same holographic reproduction accurate reproduction of object light wave when we look at the object light wave, we observe and reproduce the three-dimensional image from various angles, and we still look at realistic objects on the same side. With depth of field and parallax, we take two Mercedes-Benz cars side by side. model when we change the direction of observation, the covered part of the car will be exposed. It is no wonder that people will show a Mercedes-Benz car to take a hologram and be excited: it's too brilliant to see the car reappear like pulling the door and sitting on the 'Mercedes, the hologram is equivalent to shooting from multiple angles and focusing into many ordinary photos. The holographic information is equivalent to 100 or 1000 ordinary photos. Look at the surface of the hologram with a high-power microscope. Look at the complex stripes. Look at the image of the object. light waves and standard light waves emitted by laser illumination objects (Reference light wave) The interference plane is recorded and formed on the photosensitive bottom plate, and the object light wave is frozen by the coding method. Once the illumination light wave is similar to the reference light wave, the imaging light wave will be emitted. The original light wave will be released again. the principle is expressed in eight characters: interference recording diffraction reproduction, we use holography technology in a wide range of fields to photograph some precious cultural relics with item technology. When exhibiting, the cultural relics are truly reproduced in three dimensions for visitors to appreciate, while the original objects are properly preserved to prevent theft. Large holograms display cars. satellites and various three-dimensional advertisements also use pulse holography to reproduce portraits and wedding commemorative photos. Small holograms form beautiful decorations on the neck to reproduce people's favorite animals. Colorful flowers and butterflies develop rapidly. Molded rainbow holograms are vivid. cartoons, greeting cards and three-dimensional stamps are also used as anti-counterfeiting signs. Trademarks, ID cards, bank credit cards and even decorative books on banknotes. Holographic three-dimensional photos and holographic rainbows on gift packaging make people realize the printing technology and packaging Technology New leap compression holographic logo due to the three-dimensional layering and changes with the angle of observation rainbow effect and ever-changing anti-counterfeiting marks, coupled with its close combination of high-tech anti-counterfeiting means, the new century anti-counterfeiting technology has been pushed to a new brilliant peak
