Holographic displays scatter light at a 2D surface. If the viewer isn\u2019t looking directly at the front side of the projected image, he or she wouldn\u2019t see it as 3D. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Instead, the display is considered a volumetric image because it is a 3D image that floats in air, and one can walk around and see from all angles.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The team created a free-space platform to display full-color, aerial volumetric images. &nbsp;<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The technique involves trapping a particle in a low-visibility tractor beam, explained Smalley. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cThe tractor beam drags the particle around and as it does so the particle is illuminated to trace out a 3D image in air.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Smalley and his team are effectively printing 3D light images in space with the particles.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As explained in the study, humans cannot perceive images at rates faster than 10 per second, so if the particle is moved quick enough, it would appear as a solid line of light, similar to a sparkler on a dark night. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Smalley, like most of his colleagues, has always had \u201cmaking Princess Leia\u201d as a research goal, but until this point it had been a difficult feat. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cThe moment of clarity for me occurred during the movie Iron Man when I realized that a hologram really wasn&#8217;t going to be able to make many of the displays of science fiction,\u201d said Smalley. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cIn particular, the moment when the protagonist, Tony Stark, sticks his hand in what is ostensibly a holographic gauntlet,\u201d he continued. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cI was disturbed to realize that his hand was in front of the display blocking the light so no imagery should be visible above his arm. After some thought, the only solution I could think of that would work in this scenario would be to have a swarm of levitating nanobots with lasers shooting everywhere. It sounded crazy at the time but our current solution is not far from that idea in some respects.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Although some previous researchers have worked with volumetric images before, Smalley and his team are the first to effectively use optical trapping and color. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">So far, the team has created volumetric images of the BYU logo, a butterfly, a prism and others.<\/span><\/p>\n<p><iframe title=\"Beyond holograms: Star Wars-inspired 3D images float in free space\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/1aAx2uWcENc?feature=oembed\" frameborder=\"0\" allow=\"accelerometer;
