US Researchers have discovered a way to create real-life pictures that are aerial

US researchers have taken the inspiration of an iconic laser display seen in science-fiction films, like Star Trek and Star Wars. Their discovery is a way to build real-life pictures that are aerial. And the findings are genuinely out of this world. US researchers apply lasers and small particle free-floating in the air to produce digital pictures. These pictures can be seen without the requirement of a specific headset or smartphone. Even if we see these three-dimensional pictures from any angle, we can see them living in that space, indicating they are physical.

The study is led by Brigham Young University (BYU) professor of electrical engineering, Dan Smalley. The researchers at the Utah-based university applied laser beams to trap and illuminate a small particle in the air. They then shifted the beam, dragging the particle with it, to get an impression in the air.

During a roughly four-minute YouTube video, Smalley illustrates an augmented reality battle. The battle is among a miniature version of the following making use of the new technology:
  • USS Enterprise
  • US Navy aircraft carrier
  • Klingon Warbird from “Star Trek”

Smalley says that most 3D exhibits involve a person looking at a screen. However, the technology he and his crew members have built permits them to produce pictures floating in space. “What you are witnessing in the scenes we build is real; there is not anything that computer generates about them,” a BYU blog cited Smalley as stating.

Smalley and his crew earned national and international recognition three years ago for discovering how to draw screenless, free-floating items in space. That technology was known as “optical trap displays”. The scientists then spent three more years enhancing their OTD technology to involve real animation created in thin air.

The research, financed by a National Science Foundation CAREER grant, was first issued in the Nature Scientific Report journal. And Smalley’s thorough body of effort can be read on the website of the BYU Electro Holography Group.

The growth, the researchers say, can surface the way for people to have an immersive experience and relate with virtual objects that co-exist in their immediate space.
