Academician of the Chinese Academy of Sciences Chu Junhao showed and used at a party party.The "stealth" realized by special materials, and said, "the hidden cloak of Harry Potter in the future will be the daily necessities in the wardrobe."
According to Jimomoma News, on Saturday (October 28), a "Bilibili Super Science Evening" in Beijing on Saturday (October 28), Chu Junhao introduced the effect of "the effect of multiple optical stealth methodsTest "test" and "stealth techniques" that use special materials at the scene.
Chu Junhao said: "I can tell everyone responsibly that this is not magic, but scientific means. In the future, Harry Potter's stealth cloak will be in the wardrobe."
The video shows that Chu Junhao first asked the staff to hold a panel, and then he stood behind the panel.At first, he could see his lower body through the panel, but after the staff rotated this material 90 degrees, his lower body suddenly disappeared and turned into a stage scene behind him.
According to reports, Chu Junhao's "stealth" uses a magical material "column mirror grating" that allows light to reflect the light.This material is arranged by a row of tiny cylindrical convex mirrors to form a cylindrical light grid. Each cylindrical convex lens will compress the objects behind it into a thin strip. When the number of lenses is enoughIt seems invisible, so as to achieve the "stealth" effect visually.
Chu Junhao believes that in the future, with the gradual maturity of 'stealth' technology and 'super material', the "stealth" in science fiction will gradually move towards reality; I believe that there will be more 'stealth' equipment in the futureChange people's lives, such as the invisible room with better privacy, invisible hearing aids, etc.
Some netizens expressed their expectations for the "stealth technique" displayed by Chu Junhao, saying that "I really feel emotional after reading it, science and technology will always be updated.The imagination can be realized in the future, and I look forward to it. "" It seems that stealth clothes are no longer a dream in science fiction works "," must be necessary for people to go out. "However, some people are worried, "I don't need this item in my wardrobe, but I am afraid of the criminal's wardrobe."
According to popular science China, the "stealth" only refers to the use of eyes in a narrow sense, and the stealth is not limited to the eyes, but the use of a certain detection method (such as radar, sons)It is called to be invisible under such detection methods.Stealth technology has also become the focus of research in the military field. With the continuous development of scientific theory, stealth technology such as infrared stealth and radar stealth have been mature in the military field.
Data show that Chu Junhao, 78, is an infrared physicist, an expert in semiconductor physics and device, academician of the Chinese Academy of Sciences, researcher at the Shanghai Institute of Technology and Physics of the Chinese Academy of Sciences, and Dean of Donghua University School of Science.He has long been engaged in the research of infrared electronic materials and devices, and carried out the research on the material and device of the material and device of the narrow control band semiconductor cadmium mercury (HGCDTE) and the iron electrical film for infrared detectors.
