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 ...

Video: Holograms go 4D Holography has just gained a fourth dimension, bringing the prospect of Star Wars -style holographic telepresence into the real world. Ever since Emmett Leith and Juris ...

This holographic laser projector (HLP) projects images onto curved and tilted surfaces. We just got our hands on the tech in the back rooms of CES 2010, and it works beautifully.

Real holography requires a laser-generated 3D image, and it's no mean feat to stuff that into something you can comfortably wear. Microsoft just made some important progress, however.

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

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