Engineers Massachusetts scientific-technical Institute invented a system image projection, due to which any illusory surface can be made into a reflective screen. Description of the technology published in the journal Nature Communications, short of it can be found on the website of the Institute. The essence of the newest technologies is the use of submerged in polymer nanoparticles, which selectively scatter light only a specific wavelength. To create a screen layout scientists used the particles of silver with a diameter of 60 nanometers, which scatter blue light. The addition of small quantities of nanoparticles on the transparency of polymer virtually no effect - except, of course, the light of the wavelength at which particles specifically cooperate. Projecting on a transparent polymer light of the projector, you can see quite bright reflected a monochrome image. Polymer nanoparticles can be created in the form of narrow film that can turn the screen almost any transparent surface. Although nanoparticles consciously work solely with the light of the same wavelength, on the basis of this technology you can make and full-color transparent screens. To achieve the desired result, it is enough to apply nanoparticles 3 types that interact with red, blue and green. Curiously, but the screen still remains clear: the impact will be exclusively radiation in 3 close the bands range, and the rest of the light will pass through the screen. Engineers believe that film with nanoparticles made by this technology, can turn into a reflective screens window dwellings, glass machines and other large transparent plane. Existing technologies overlay image or greatly reduce transparency, or, as in prismatic Google Glass, require strict positioning of the observer. <iframe width="560" height="315" src="//www.youtube.com/embed/0aw58MUciWw?rel=0" frameborder="0" allowfullscreen></iframe>
