3D laser holograms sound cool, but they're generally hot. As in, hot enough to burn your skin. But now researchers at the Digital Nature Group, a Japanese lab, say they've figured out a way to ...

To create their hologram, researchers fired their femtosecond laser through a spatial light modulator, which continues the beam through a series of lenses, a mirror and a Galvano scanner, which ...

By combining the geometric phase with plasmonic metasurfaces, it is possible to make wide-angle holograms with power efficiency of 80% over a broad range of frequencies.

In my description of holography above, the 2D pattern is formed from two light fields: one has only scattered from the object and one has not scattered at all. This is why we use lasers: the laser ...

The development of hologram technology started in 1962, when Yuri Denisyuk, in the Soviet Union, and Emmett Leith and Juris Upatnieks at the University of Michigan developed laser technology that ...

Laser Holograms Can Be Touched and Felt. Laser Holograms Can Be Touched and Felt. Haptic holograms! By John Wenz Published: Jul 02, 2015 6:00 PM EDT. Save Article. Media Platforms Design Team.

Even though it was invented over 70 years ago, holography remains the best candidate for achieving true 3D displays. Here we present six things you may not know about the strange and wonderful ...

K Laser Technology, a manufacturer of holographic and metalized substrates, is set to exhibit its offset KOLDfoil ONE and Viridian Eco-Paperboard substrates at Print UV 2023.

To make a hologram of something like a 3D fingermark, researchers split light from a laser into two parts. One part, called the reference wave, shines directly on a digital camera.

K Laser Technology will be highlighting Viridian™ holographic eco-paperboard®, a fully recyclable and sustainable, yet luxurious and stunning alternative to laminated product packaging.
