Belgium develops holographic television to replace existing 3D technology

According to foreign media reports, in recent years, holographic television technology has become an increasingly hot topic in the industry, and countries in the world have also achieved certain results in the research of holographic television technology. Perhaps in the near future, holographic television can appear in our real life. Recently, a research institute in Belgium proposed a completely new implementation plan, which may soon be able to present real holographic images to people.

Holographic television is a new form of television. It will bring people a completely different visual and audio experience from traditional television. Scientists at the famous Microelectronics Research Center in Leuven, Belgium, believe that today's 3-D TVs or images can cause problems such as visual fatigue and headache dizziness that will be completely solved by holographic imaging technology.

At the Microelectronics Research Center, one of the scientists' major research work is to create moving pixels. They irradiate the laser to the platform of the microelectromechanical system to create a holographic display. This platform can be moved up and down like a small reflective piston to move pixels. The Microelectronics Research Center claimed 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, eyestrain, and mental stress."

In the microsystem developed by the Microelectronics Research Center, silicon dioxide is embedded in a chip with a square patch to form a Western checkerboard pattern. Then, the upper layer of the chip is coated with a reflective aluminum film. When the laser light hits the chip, the chip reflects the reflected light from the nearby pixels at an angle. The diffracted light interferes constructively or destructively with each other, thus forming a 3-D image. At this point, these small reflecting platforms move up, down, left, and right several times a second, creating a moving projection.

The Microelectronics Research Center hopes to develop the first proof of concept mobile architecture by the middle of 2012. The agency claims that "the microelectronics research center's program may be the ultimate technology for future 3-D displays, which have a 60-degree diffraction angle and a high-resolution visual experience."

In addition to microelectronics research centers, there are many research institutes around the world that are also working on holographic imaging problems. According to reports, in 2011 several research teams claimed that they have made significant progress in this area and are moving closer to real holographic television technology. Scientists at the Massachusetts Institute of Technology also claimed that they have developed a holographic television system with a refresh rate of 15 frames per second. In early 2011, the U.S. Department of Defense’s Advanced Research Projects Agency completed a five-year research project called “Urban Optical Sand Table Display System.” According to reports, this system can form a true 360-degree 3-D color holographic image.
