![]() ![]() Smalley and his coauthors have devised a free-space volumetric display platform, based on photophoretic optical trapping, that produces full-color, aerial volumetric images with 10-micron image points by persistence of vision. Examples of volumetric images include the 3D displays Tony Stark interacts with in "Iron Man" or the massive image-projecting table in "Avatar." A 3D image that floats in air, that you can walk all around and see from every angle, is actually called a volumetric image. The image of Princess Leia is not what people think it is: It’s not a hologram. We have created a display that can do that.”įirst things, first, Smalley says. “Our group has a mission to take the 3D displays of science fiction and make them real. “We refer to this colloquially as the Princess Leia project,” Smalley said. In a paper published this week in Nature, Smalley details the method he has developed to do so. The iconic scene includes the line still famous 40 years later: “Help me Obi Wan Kenobi, you’re my only hope.”īYU electrical and computer engineering professor and holography expert Daniel Smalley has long had a goal to create the same type of 3D image projection. In the original Star Wars film, R2D2 projects an image of Princess Leia in distress.
