Help the holographic world's thinnest bubble projection screen turned out?

'Ah! My projection screen is broken! Blow another one!' 　　 It may not be long before the above seemingly jokes can happen in real life. The continuous development of science and technology has brought various surprises to mankind. In terms of display screens, fresh designs are also emerging one after another. As a technology expert, what hot terms can you say? Retina? OLED? If you only know these, it's really OUT. Helping holography Japan develops the world’s thinnest bubble projection screen 　　　　　 Can a screen be made with soap bubbles? And can achieve 3D and holography? This product is currently appearing in Japan and will be exhibited in August. This technology is very beneficial to the development of holographic projection. Before telling the reasons, please take a look at the specific news of the bubble screen.　　 Bubble Screen　　　 Yoichi Ochiai of the University of Tokyo in Japan has made the world’s thinnest soap bubble projection screen, which can display vivid and vivid two-dimensional images, 3D effects and even holographic projection.　　 Compared with the traditional opaque screen, the picture of the new screen is more contagious. This screen can use the ultrasonic waves generated by the speaker to change the 'texture' of the bubble surface and produce different effects. Using a single projector, you can image and change the effect of the image to make it smoother or rougher.　　Using two or more bubbles with different transparency to overlap the screen can produce a 3D effect. In addition, since the bubble is firm, it is not afraid of being broken, so users can interact with it.　　The designer said that this kind of screen is conducive to the artist to display more vivid images. On a transparent screen, the image of the object displayed seems to be independent of the air, which will make the viewer more interested in enjoying the image.　　What is a holographic 　　　Is this new type of screen 'breakable'? The answer is no. Although I don’t know why, the designers say that it has interactive functions, and if it has multiple screens at the same time, it can also display 3D effects, even holographic projection. This kind of projection screen blown out with soap bubbles will be exhibited at SIGGRAPH 2012 in Singapore in August. At that time, you will be able to solve the problem. So why is this technology beneficial to holographic projection? What is holographic projection?　　 holographic technology is actually to realize the recording and reproduction of real three-dimensional images. The record problem was overcome as early as 1947. The holographic projection is the reverse display of this process. The general three-dimensional image only realizes the three-dimensional perception of the human eye through the composition and color changes on a two-dimensional plane, while the hologram produced by holographic stereo photography contains information such as the size, shape, brightness and contrast of the recorded object. Provide 'parallax'. The observer can observe different images of the image by moving back and forth, left and right, and up and down-as if there is a real object there.　　 There are many ways to realize holography at present, through a special film source and ordinary projector, the projection beam is hit on the water vapor, high-speed rotating lens, or a special holographic projection film. At present, the most common method is to use holographic projection film, and the biggest drawback of this method is the high cost, and the holographic projection film is expensive.　　 Favorable promotion 　　　 The 'new work' of Japanese researchers is a way to use water vapor to form a holographic projection effect. Previously, there was a small-scale blasting in the air that was continuously achieved, thereby using the water vapor in the air to form a holographic scheme. But this kind of scheme is somewhat dangerous, because the possibility of use is not high. Can beautiful bubbles really be used for projection? The use of soap bubbles to demonstrate the holographic projection effect is undoubtedly not dangerous. This solution is simple and easy to operate. More importantly, its cost is also very low. The holographic projection film is expensive due to complex technology and patents, so bubble imaging is used. , There is no such ill at all.　　If it can be maturely used in production, then this new type of screen is of great significance for holographic projection. Its cheap cost is conducive to the promotion of holographic projection. However, issues such as image clarity and screen sturdiness remain to be witnessed.
