Brigham Young University today shared with us a look at their photophoretic-trap volumetric display that they refer to as the "Princess Leia Project."
Check out the video.
"This display is like a 3D printer for light. You’re actually printing an object in space with these little particles." - Daniel Smalley, BYU electrical engineering professor. BYU engineers have developed a technique for creating a full-color 3D graphic display that can float in free space and is visible from any angle. Inspired by the displays of science fiction--most notably the iconic Star Wars' Princess Leia projection - the new Optical Trap Display (OTD) technique, creates a 3D volumetric image by trapping and illuminating a particle with a laser, and then scanning the image in free space. Unlike a hologram, a volumetric image is created in free-space and is visible from any angle. BYU electrical engineering professor Daniel Smalley and co-authors publish their research ("A photophoretic-trap volumetric display") in the January 24, 2018, issue of the journal Nature.
