This concept was inspired by Star Wars and Star Trek that used lasers to create the displays of science fiction. Researchers found a way to create moving, free-floating images in the air like a 3D image. They can be tiny weapons but BYU’s holography research group has figured out how to create lightsabers green for Yoda and red for Darth Vader, naturally with actual luminous beams rising from them.The team of researchers have also engineered battles between equally small versions of the Starship Enterprise and a Klingon Battle Cruiser that incorporate photon torpedoes launching and striking the enemy vessel that you can see with the naked eye.
Dan Smalley, a professor of electrical engineering at BYU and the lead author of the study said that the science they create is real which is nothing computer-generated. This is not like the movies, where the lightsabers or the photon torpedoes never existed in physical space. They are real, and if you look at them from any angle, you will see them existing in that space.
The research group’s project is funded by a National Science Foundation CAREER grant, goes to the next level and produces simple animations in thin air. The development gives the way for an immersive experience where people can interact with holographic-like virtual objects that coexist in their immediate space.Smallest added that the 3D image requires you to look at a screen, but our technology allows us to create images floating in space and they’re physical images. This technology can make it possible to create vibrant animated content that orbits around or crawls on or explodes out of everyday physical objects.
