Researchers use lasers to display ‘true’ 3-D objects
In an iconic scene in Star Wars, R2-D2 delivers a three-dimensional projection of a desperate Princess Leia pleading, “Help me Obi-Wan Kenobi. You’re my only hope.” The 3-D display that was once only a mainstay of science fiction is now closer to reality, thanks to technology developed by a team of researchers at the University of Rochester.
