Holograms like in Star Wars.

Using carefully prepared nanomaterials, scientists at Tokyo University of Agriculture and Technology succeeded in “bending” the laser beam in such a way that a holographic image with previously unattainable properties was created, which observers compared with the holograms known from the "Star Wars" series . Thanks to the new technology, the image of a rotating globe was created. The work of the Japanese research team was described in the journal "Optics Express".

So far, the visual effect is not perfect. The hologram itself consists of only forty-eight individual images. At a time when the artists' holograms are seen on stage in much better quality, this doesn't seem like a great achievement. But it's a delusion. Japanese technology is much more advanced, it allows three-dimensional images to be seen from all sides and does not use optical "tricks" that fool the eye.
In order to break down the laser light so that a three-dimensional image of the globe is created, special "scales" that are smaller than the wavelength of the red laser light are made of nanomaterial through which the beam passes. This material takes a long time to prepare. The researchers estimate it would take 800 hours to prepare them using the six-minute hologram technique. But they still have high hopes. "Our goal is to develop this technology to the point where we can finally get full color," explains engineer and research author Kentaro Iwami in a press release that was published in the media.
