Use lasers to create a Star Wars and Star Trek-inspired science fiction display.

They may be small weapons, but BYU’s holography research group has come up with a way to create a lightsaber (green for Yoda, red for Darth Vader) with a real emission beam.

Inspired by science fiction exhibits, researchers have found a similarly small version of the Starship Enterprise and the Klingon battle cruiser, incorporating photon torpedoes that launch and attack enemy ships that are visible to the naked eye. I also designed the battle.

“What we see in the scenes we create is real. No computers have been generated for them,” said Dan Smalley, a senior researcher at BYU’s professor of electrical engineering. “This is different from movies where lightsaber and photon torpedoes didn’t really exist in physical space. They are real and you can see that they are in that space from any angle. I will. “

BYU’s holography research team is using lasers to create displays of science fiction inspired by Star Wars and Star Trek. A video produced by Julie Walker.

This is the latest work by Smalley and his research team, who received national and international attention three years ago when they found a way to draw a free-floating object without a screen into space. These displays, called optical trap displays, are created by trapping a single particle in the air with a laser beam and moving the particle, leaving behind a laser irradiation path that floats in the air. It’s like a “3D printer for light”.

A new project in a research group funded by the National Science Foundation’s Career Grant takes it to the next level, creating simple animations in thin air. This development paves the way for an immersive experience where people can interact with virtual objects such as holographic that coexist in familiar spaces.

“Most 3D displays require you to look at the screen, but our technology allows you to create images that float in space. These are physical. Not some mirages,” Smalley said. “This technology allows us to create vibrant animated content that orbits, crawls, and explodes everyday objects.”

To demonstrate that principle, the team created a virtual stickman walking in the thin air. They were able to show the interaction between virtual images and humans by having students place their finger in the center of the volume display and then walk the finger of the same stick and jump off that finger.

Smalley and Rogers elaborate on these and other recent breakthroughs. A new treatise published in Nature Scientific Reports last month.. This task overcomes the limiting factors of optical trap displays. Since this technology does not have the ability to display virtual images, Smalley and Rogers have shown that virtual images can be simulated using a time-varying perspective background.

“You can use motion parallax to do some elaborate tricks and make your display look much bigger than the physical one,” Rogers said. “This methodology can create the illusion of a much deeper display, even to a display of theoretically infinite size.”
