Holography in Pocket: Turning iPhone Portraits into Full-Parallax 3D Images

Holography, once the domain of high-energy lasers and complex camera arrays, is now entering the realm of everyday consumer technology. A recent study published in Optics Letters demonstrates how a single smartphone – specifically, an iPhone 13 Pro – can be used to generate full-parallax holographic portraits, offering a low-cost and accessible alternative to traditional methods.
