In this paper, we present two approaches for recording a quasi-hologram on the steel surface by femtosecond laser pulses. The recording process is done by rotating the polarization of the laser beam ...

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 ...

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 ...

To synthesize a holographic color image, one can sequentially take three holograms at different wavelengths, e.g., at red (R), green (G) and blue (B) parts of the spectrum and digitally merge them. To ...

In two new studies, researchers at UCLA used artificial neural networks to reconstruct a hologram — not just any hologram, though. Not only is the technique an advancement of holographic technology, ...

(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 ...

In the darkened Wiltern Theatre in Los Angeles, hundreds of people couldn’t wait to see legendary rocker Roy Orbison. A live orchestra pumped up the crowd with a medley of his hits. Old photos of him ...

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 ...

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 ...

Stereoscopes entertained every Victorian home with their ability to produce three-dimensional pictures. Typewriters and later fax machines were once essential for business practices. Photo printers ...
