Beijing time, January 4, according to foreign media reports, in recent years, holographic TV technology has become an increasingly popular topic in the industry, and countries around the world have also achieved certain results in the study of holographic TV technology. Perhaps in the near future, holographic TV will be able to appear in our real life. Recently, a Belgian research institute has proposed a brand-new implementation scheme, which may soon be able to present real holographic images to people.
Holographic vision can provide a natural 3-D experience for many viewers
Holographic TV is a brand-new TV form, it will bring people a completely different audio-visual experience from traditional TV. Scientists at the famous Microelectronics Research Center, headquartered in Leuven, Belgium, believe that the problems of visual fatigue and headaches and dizziness brought about by today's 3-D TVs or images will be completely solved by holographic image technology.
At the Microelectronics Research Center, one of the important research work of scientists is to create moving pixels. They irradiated the laser on the micro-electromechanical system platform to build a holographic display, which can move up, down, left, and right like a small reflective piston to achieve the effect of moving pixels. The Microelectronics Research Center claims that “holographic vision can provide a natural 3-D experience for many viewers without the unpleasant side effects of today ’s 3-D stereo vision, such as troublesome 3-D Glasses, tired eyes and nervousness. "
In the microsystem developed by the Microelectronics Research Center, silicon dioxide is embedded on the chip in patches of squares, forming a checkerboard pattern. Then, a layer of reflective aluminum film is plated on the upper layer of the chip. When the laser is irradiated on the chip, the chip will reflect the reflected light of adjacent pixels at an angle. The diffracted rays interfere constructively or destructively with each other, thus forming a 3-D image. At this time, these small reflective platforms move up, down, left, and right several times per second to form a moving projection.
The Microelectronics Research Center hopes to develop the first proof-of-concept version of the mobile structure by mid-2012. The agency claimed that "the program of the Microelectronics Research Center may become the ultimate technology for future 3-D displays, that is, this holographic display has a 60-degree diffraction angle and high-resolution visual experience.
In addition to the microelectronics research center, several research institutions around the world are also working on holographic imaging problems. According to reports, several research teams claimed to have made important progress in this field in 2011, moving closer to true holographic TV technology. Scientists at the Massachusetts Institute of Technology also claimed that they have developed a holographic TV system with a refresh rate of 15 frames per second. In early 2011, the US Department of Defense Advanced Research Projects Agency completed a five-year research project-"Urban Optical Sand Table Display System". According to reports, this system can form a true 360-degree 3-D color holographic image.
