Holographic light modulation is the most efficient method to shape laser light into well-defined patterns and is therefore the means of choice for many intensity demanding applications. During the ...

Holograms record and display realistic three-dimensional images that appear to float over a surface. One day they might be used to immerse viewers in virtual worlds or simply provide ultra-realistic ...

Sound holography has shown great capability in reconstructing the arbitrary complex sound fields, with potential applications in various scenarios. To overcome the limitations of existing technologies ...

(Phys.org)—By carefully arranging many nanoblocks to form pixels on a metasurface, researchers have demonstrated that they can manipulate incoming visible light in just the right way to create a color ...

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, ...

The room is dark. There's a quiet whirr of fans. Nature sounds play from unseen speakers. One wall is decorated with what I assume is artificial greenery. In the center, a head. Blue and purple and ...

When Shawn Frayne was just a 10 year old in Orlando, Florida, his dad took him to see Back to the Future 2, which set the trajectory for his life-long passion to advance hologram technology. He was ...

This is the third and final article in a series on 3D imaging, this time looking at the promises, real and otherwise, of the holographic display. No discussion of 3-D imaging should ignore the ...

Future Apple AR devices, such as "Apple Glass," may include holograms to make moving through virtual environments feel more natural. Apple has already very many patents and patent applications ...

I don’t know about you guys, but my brain has a really hard time comprehending things like 3D printing and holograms. Like, I get that they’re real things that exist, but how they work makes no sense ...

Count me among those who have no desire to see Whitney Houston resurrected on stage – or Amy Winehouse, Roy Orbison or any of the other dead celebrities modern technology now enables the world to ...
