The difference between holography and photography can be summarized perhaps most succinctly as the difference between recording the effect photons have on a surface, versus recording the wavefront ...

Particles of twisted light that have been entangled using quantum mechanics offer a new approach to dense and secure data storage. Holograms that produce 3-D images and serve as security features on ...

Scientists have created a new device small enough to fit inside of a regular pair of glasses. This new design could help solve one of the primary issues surrounding the use of holographic displays by ...

Recently, a research team from Pohang University of Science and Technology (POSTECH) has employed metasurfaces to fabricate angle-dependent holograms with multiple functions. This technology allows ...

Counterfeiting of various documents, banknotes, or tickets is a common problem that can be encountered in everyday life, even when shopping. Recognizing the scale and seriousness of the problem, ...

Scientists have created “acoustic holograms” that can assemble matter into 3D objects, using just sound. The technique works with various types of particles and even living cells, allowing for a new ...

Researchers developed a new smartphone-based digital holographic microscope that enables precision 3D measurements. The highly portable and inexpensive microscope could help bring 3D measurement ...

Bari Hoffman first learned of holograms during the pandemic, when she saw that rapper Diddy had beamed a full-body digital version of himself into a seven-foot-tall display box to remotely sing “Happy ...

Terminal B at LaGuardia Airport in New York has unveiled Bridget, a life-sized, hyper-realistic AI hologram that can hold a real conversation – answering questions about gates, baggage claims, and VIP ...
