Researchers develop a method to project holograms onto iPhone displays

In 2012, as lines formed outside the Apple Store on Fifth Avenue in New York City ahead of the iPhone 5’s release, a local Fox News affiliate showed how the iPhone 5 would feature a laser keyboard and holographic display. reported. Of course, the iPhone 5 didn’t have anything like that. Reporters confused Aatma Studio’s concept iPhone 5 video with features found on the actual device.

Looking ahead 12 years, those features will not be available in the iPhone 16 series, which will be released in September this year. However, according to an article published by the researchers in Optics Letters (via BGR), 3D holographic images can be created using a touchscreen iPhone display. Holographs typically require the use of expensive and complex lasers, so being able to create them using an iPhone is a major advance.

Using an iPhone does not make hologram creation any less complex. This is a summary of the researcher’s paper, which is an overview of the research conducted, the research methodology, and the author’s findings.

“We present a method of computer-generated holography (CGH) that uses incoherent light emitted from a mobile phone screen. In this method, the first hologram is a color image displayed on the mobile phone screen. Assume a hologram cascade with a two-layer hologram cascade consisting of an iPhone and a spatial light modulator. Demonstrates reproduction of 3D color images.
