It’s one of those grandiose ideas that gets bandied about by Pentagon scientists and pops up in the press every few years. The “Face of Allah” weapon would beam a massive, lifelike hologram over a battlefield, projecting the image of some deity “to incite fear in soldiers on a battlefield,” according to one researcher.

We last checked in on holographic weapons research two years ago, when the University of New Hampshire was working on some Pentagon-funded projects. Since then, another university team has turned holograms into a reality — but not as tools of war. Not yet, at least.

Optical scientist Nasser Peyghambarian and his teammates at the University of Arizona have demonstrated what The New York Times calls “actual moving holograms that are filmed in one spot and then projected and viewed in another spot.” The Times likens the holograms to the tiny image of Princess Leia that R2D2 showed Luke Skywalker in the beginning of Star Wars, only “a lot more haltingly, as the display changes only every two seconds.”
