Researchers made a holographic display from a plain old iPhone 14 screen

Science fiction often relies heavily on holographics to showcase the future of technology. For the most part, though, holographic tech has always seemed a bit outside our wheelhouse, with the tech needed to create realistic holographic displays being exceptionally expensive. Now, though, researchers have done it with an ordinary iPhone screen. Currently, the only way we've been able to make holographic displays is by using complex and expensive laser emitters.

The second layer, though, was projected by the screen taken from an iPhone 14. This allowed the researchers to coordinate the images to create a realistic-looking holographic display that looked very similar to those created by expensive laser systems. Despite how simple it might seem, this approach is highly complex, and it requires a lot of careful modeling to create the algorithm responsible for coordinating the light from the screen and the spatial light modulator.
