Japanese scientists managed to create a real hologram in the spirit of “Star Wars”

TECHNOLOGY

Scientists at the Tokyo University of Agriculture and Technology have developed a method to create holograms similar to those shown in the movie “Star Wars”.

To do this, the engineers used carefully selected nanomaterials, with the help of which they achieved a refraction of light that cannot be achieved with any natural material. As a result, the first full-fledged holographic video was created, demonstrating the rotation of the Earth around its axis.

The main difference from all existing holograms is that this is a really three-dimensional image – the globe can be walked around and viewed from different sides without any optical illusion.

The resulting effect can hardly be called cinematically perfect: the noticeably pulsing hologram is just a “picture” of a spinning globe of 48 frames, which resembles the graphics of the Nintendo Virtual Boy.

To refract a laser in the right way, the nanomaterial must have tiny flakes that are much smaller than the wavelength of the laser’s light. The creation of such material, according to the researchers, takes time. So, to form a six-minute hologram, at least 800 hours of preparation are required. But the development has already begun.
